Outcomes of Completion Lobectomy for Locoregional Recurrence after Sublobar Resection in Patients with Non-small Cell Lung Cancer.

This retrospective study aimed to determine the treatment patterns and the surgical and oncologic outcomes after completion lobectomy (CL) in patients with locoregionally recurrent stage I non-small cell lung cancer (NSCLC) who previously underwent sublobar resection. Data from 36 patients who initially underwent sublobar resection for clinical, pathological stage IA NSCLC and experienced locoregional recurrence between 2008 and 2016 were analyzed. Thirty-six (3.6%) of 1,003 patients who underwent sublobar resection for NSCLC experienced locoregional recurrence. The patients' median age was 66.5 (range, 44-77) years at the initial operation, and 28 (77.8%) patients were men. Six (16.7%) patients underwent segmentectomy and 30 (83.3%) underwent wedge resection as the initial operation. The median follow-up from the initial operation was 56 (range, 9-150) months. Ten (27.8%) patients underwent CL, 22 (61.1%) underwent non-surgical treatments (chemotherapy, radiation, concurrent chemoradiation therapy), and 4 (11.1%) did not receive treatment or were lost to follow-up after recurrence. Patients who underwent CL experienced no significant complications or deaths. The median follow-up time after CL was 64.5 (range, 19-93) months. The 5-year overall survival (OS) and post-recurrence survival (PRS) were higher in the surgical group than in the non-surgical (p<0.001) and no-treatment groups (p<0.001). CL is a technically demanding but safe procedure for locoregionally recurrent stage I NSCLC after sublobar resection. Patients who underwent CL had better OS and PRS than patients who underwent non-surgical treatments or no treatments; however, a larger cohort study and long-term surveillance are necessary.

Laparoscopic anatomical versus non-anatomical liver resection for hepatocellular carcinoma in the posterosuperior segments: a propensity score matched analysis.

Since laparoscopic anatomical resection (LAR) for tumors, especially located in the posterosuperior (PS) segments of the liver remains difficult, laparoscopic non-anatomical resection (LNAR) are generally preferred. To compare the clinical outcomes between LAR and LNAR for hepatocellular carcinoma (HCC) located in the PS segments. We retrospectively reviewed the data for 1,029 patients who underwent hepatectomy for HCC between 2004 and 2019. Of 167 patients who underwent laparoscopic hepatectomy for HCC in PS segments, 64 underwent LNAR and 103 underwent LAR. Patients were matched one-to-one using propensity score matching (46:46). LNAR was associated with significantly shorter operation time (P=0.001), lower estimated blood loss (P=0.001), lower transfusion rate (P=0.006) and shorter hospital stay (P=0.012) than LAR. The respective 1- ,3-, and 5-year overall survival rates (LAR: 95.3%, 87.1%, and 77.8%; LNAR: 96.7%, 91.6%, and 85.0%; P=0.262) and recurrence-free survival rates (LAR: 75.7%, 70.3%, and 68.9%; LNAR: 81.8%, 58.3%, and 55.3%; P=0.879) were similar. The intrahepatic recurrence rate was significantly higher in LNAR group than in LAR group (78.6% vs. 57.1%, P=0.023), but the post-recurrence treatments differed significantly between the two groups (P=0.016); the re-resection rate was much greater in the LNAR group (45.0% vs. 0%) group. The respective 1-, 3-, and 5-year post-recurrence survival rates were similar in the LAR and LNAR groups (P=0.212). After recurrence, survival in re-resection group was significantly greater than not (P=0.026). LNAR is safe and feasible for HCC located in PS segments, and provided acceptable oncologic outcomes that are comparable to those of LAR. LNAR can be considered for patient with tumor located in PS segment when LAR is not feasible.

Preoperative predictors for recurrence sites associated with poor post-recurrence survival after surgery of non-small cell lung cancer: a multicenter study

BackgroundThe recurrence site that influences post-recurrence survival (PRS) in patients with non-small cell lung cancer (NSCLC) undergoing surgery and the preoperative predictors of recurrence remain unclear.MethodsCohorts 1 and 2 had 4520 (who underwent complete resection for p-stage 0-IIIA NSCLC) and 727 (who experienced recurrence after surgery) patients, respectively. The initial sites of recurrence were the lungs (309 cases), thoracic lymph nodes (225 cases), pleura (112 cases), bone (110 cases), central nervous system (86 cases), adrenal gland (25 cases), abdomen (60 cases), cervical and axillary lymph nodes (38 cases), chest wall (13 cases), skin (5 cases), and eye and tongue (3 cases). For cohort 2 analysis, the initial recurrence site that resulted in poor PRS was analyzed by multivariable analysis using a Cox proportional hazard model. For cohort 1 analysis, the preoperative predictors of recurrence patterns with poor PRS were analyzed by multivariable analysis using a logistic regression model.ResultsIn cohort 2 analysis, recurrence in the central nervous system (hazard ratio [HR], 1.70; p < 0.001), bone (HR, 1.75; p < 0.001), abdomen (HR, 2.39; p < 0.001), and pleura (HR, 1.69; p < 0.001) were independent poor prognostic recurrent sites for PRS and they were high-risk sites (HRS). Intrathoracic lymph nodes, cervical and axillary lymph nodes, lungs, chest wall, adrenal gland, eye and tongue, and skin were low-risk sites (LRS) that did not affect PRS. Patients with multiple LRS without HRS recurrence had a worse prognosis than those with a single LRS without HRS recurrence (5-year PRS 20.2% vs. 37.7%, p < 0.001) and were comparable to those with HRS recurrence (p = 1.000). In cohort 1 analysis, preoperative predictors for HRS and multiple LRS recurrences were positron emission tomography (PET) maximum standardized uptake value (maxSUV) ≥ 3.2 (HR, 5.09; p < 0.001), clinical nodal metastasis (HR, 2.00; p < 0.001), tumor size ≥ 2.4 cm (HR, 1.96; p < 0.001) and carcinoembryonic antigen (CEA) ≥ 5 ng/ml (HR, 1.41; p = 0.004). The cumulative incidence rates of HRS and multiple LRS recurrences within 5 years were 55.9%, 40.9%, 26.3%, 11.1%, and 3.5% (p < 0.001) in patients with 4, 3, 2, 1 and 0 of the above risks, respectively.ConclusionsHRS and multiple LRS were vital recurrences associated with poor PRS. Preoperative PET maxSUV, clinical nodal metastasis, tumor size, and CEA level predicted the incidence of vital recurrence.

Defining nomograms for predicting prognosis of early and late recurrence in gastric cancer patients after radical gastrectomy.

There are few studies on the predictive factors of early recurrence (ER) and late recurrence (LR) of advanced gastric cancer (GC) after curative surgery. Our study aims to explore the independent predictors influencing the prognosis between ER and LR in patients with advanced GC after curative intent surgery respectively. And we will further develop nomograms for prediction of post recurrence survival (PRS). Data of patients with GC who received radical gastrectomy was retrospectively collected. Recurrence was classified into ER and LR according to the 2 years after surgery as the cutoff value. Multivariate Cox regression analyses were used to explore significant predictors in our analysis. Then these significant predictors were integrated to construct nomograms. The 1-, 2- and 3-year probabilities of PRS in patients with ER were 30.00%, 16.36% and 11.82%, respectively. In contrast, the late group were 44.68%, 23.40%, and 23.30%, respectively. Low body mass index (hazard ratio [HR] = 0.86, P = .001), elevated monocytes count (HR = 4.54, P = .003) and neutrophil-lymphocyte ratio (HR = 1.03, P = .037) at the time of recurrence were risk factors of PRS after ER. Decreased hemoglobin (HR = 0.97, P = .008) and elevated neutrophil-lymphocyte ratio (HR = 1.06, P = .045) at the time of recurrence were risk factors of PRS after LR. The calibration curves for probability of 1-, 2-, and 3-year PRS showed excellent predictive effect. Internal validation concordance indexes of PRS were 0.722 and 0.671 for ER and LR respectively. In view of the different predictive factors of ER and LR of GC, the practical predictive model may help clinicians make reasonable decisions.

Distinct Recurrence Pattern and Survival Outcomes of Invasive Mucinous Adenocarcinoma of the Lung: The Potential Role of Local Therapy in Intrapulmonary Spread.

Invasive mucinous adenocarcinoma (IMA) is distinct from non-mucinous adenocarcinoma, but studies on recurrent IMA are scarce. Thus, this study aimed to evaluate the recurrence patterns of IMA and the role of pulmonary local therapy (LT) in resectable pulmonary recurrence of IMA. The study reviewed 403 patients with surgically resected IMA between 1998 and 2018. The recurrence patterns were categorized as solitary pulmonary recurrence (SPR), multiple pulmonary recurrence (MPR), and extra-pulmonary recurrence (EPR). The clinicopathologic characteristics, overall survival (OS), and post-recurrence survival (PRS) were analyzed according to the recurrence pattern and LT administration. Recurrences were found in 91 (22.6%) patients, including 18 patients with SPR, 37 patients with MPR, and 36 patients with EPR. Compared with the MPR and EPR groups, the SPR group had a longer disease-free interval (32.5 vs. 9.6 vs. 10.1 months, respectively; p < 0.01) and a better OS (5-year OS: 88.5%, 41.5%, and 22.9%, respectively; p < 0.01). In case of resectable pulmonary recurrence, pulmonary LT was administered to 15 patients with SPR and 3 patients with MPR. These patients showed a better 5-year PRS than the other patients with pulmonary recurrence (86.3% vs. 30.4%; p < 0.01). Notably, long-term survival was observed for one patient with MPR undergoing LT and two patients with SPR undergoing a second LT for a second pulmonary recurrence. In this series, the patients with recurrent IMA showed different prognoses according to the recurrence pattern. The patients with pulmonary recurrence of IMA undergoing LT showed a favorable prognosis, suggesting the potential role of LT for resectable pulmonary recurrence of IMA.

Isolated lymph node recurrence in epithelial ovarian cancer-management and outcome.

The aim of our study was to assess the clinical outcome of isolated lymph node recurrence in patients with epithelial ovarian cancer treated by surgery and to analyze the impact of various clinico-pathological factors on prognosis. We conducted a retrospective analysis of all the epithelial ovarian cancer patients who underwent secondary lymphadenectomy surgery for isolated lymph node recurrence at our institute from 2013 to 2020. Univariate analysis of various factors influencing the post-recurrence disease free survival and post-recurrence survival was done using Kaplan-Meier for categorical variables and cox-proportional hazard progression for continuous variables. A total of 21 patients of isolated lymph node recurrence were treated surgically during the study period. The median disease free interval to develop lymph nodal recurrence was 13 months. All the patients achieved complete resection to no gross residual disease without any significant morbidity associated with the procedure. The median post-recurrence disease free survival after treatment of lymph node recurrence was 25 months with 3-year post-recurrence survival of 72% and 3-year overall survival of 85%. Amongst the factors influencing post-recurrence disease free survival, young age (<50 years), para-aortic lymph node dissection at initial surgery and single site of lymph node recurrence were significantly associated with better prognosis. A single site of lymph node recurrence was associated with significantly better post-recurrence survival. Complete resection is feasible for epithelial ovarian cancer patients presenting with isolated lymph node recurrence, without any significant perioperative morbidity. When combined with postoperative adjuvant chemotherapy, complete resection is associated with favourable survival outcomes. Young age, para-aortic lymph node dissection during primary surgery and single site of lymph node recurrence are associated with better prognosis.

Viral Status and Treatment Efficacy in Recurrent Hepatocellular Carcinoma After Primary Resection

BackgroundThe impact of viral background on long-term effectiveness of different treatment modalities for recurrent hepatocellular carcinoma (HCC) was not fully analyzed. MethodConsecutive 726 patients who developed intrahepatic recurrence after primary hepatectomy for HCC between 2008 and 2015 were retrospectively studied. Post-recurrence survival (PRS) and rerecurrence-free survival (R-RFS) and risk factors were analyzed. ResultsAfter a median follow-up period of 56 months, the 5-year PRS rates of the patients who underwent rehepatectomy, radiofrequency ablation (RFA), and transarterial chemoembolization (TACE) were 79.4%, 83.0%, and 54.6%, respectively. The treatment benefit for PRS was consistently observed in patients with hepatitis B virus (HBV) and non-B, non-C subgroups, but not hepatitis C virus (HCV). For patients with late recurrence of HCC, R-RFS was superior in HBV subgroup and HCV subgroup which received antiviral treatment (compared to naïve HCV subgroup). Survival difference triaged by viral status was lost in the counterpart with early recurrence. Overall, RFA improved PRS and R-RFS in patients receiving antiviral treatment. ConclusionTo achieve long-term survival after HCC recurrence, rehepatectomy and RFA were comparably effective, particularly among those with HBV. Antiviral treatment complemented survivals of patients with HCV after RFA, particularly in late first recurrence.

Influence of the initial recurrence site on prognosis after radical surgery for colorectal cancer: a retrospective cohort study

Background & AimsIn this retrospective study, we aimed to elucidate how the initial recurrence site influences the post-recurrence survival (PRS) after the curative resection of colorectal cancer.Patients and methodsWe collected samples from patients with stage I-III colorectal adenocarcinoma who were admitted to Yunnan Cancer Hospital from January 2008 to December 2019. Four hundred and six patients who developed recurrence after radical resection were included. The cases were classified according to the original site of recurrence as follows: liver metastases (n = 98), lung metastases (n = 127), peritoneum (n = 32), other individual organ (n = 69), two or more organs or sites (n = 49), and local recurrence (n = 31). Kaplan–Meier survival curves were used to compare the PRS of patients with different initial sites of recurrence. The influence of the initial recurrence site on PRS was analyzed using the Cox proportional hazards model.ResultsThe 3-year PRS of simple liver metastasis was 54.04% (95% CI, 45.46%-64.24%), and the 3-year PRS of simple lung metastasis was 50.05% (95% CI, 42.50%-58.95%). No significant difference was observed between simple liver metastasis or simple lung metastasis and local recurrence with a 3-year PRS of 66.99% (95% CI, 53.23%-84.32%). The 3-year PRS for peritoneal metastases was 25.43% (95% CI, 14.76%-43.82%), and the 3-year PRS for two or more organ sites was 34.84% (95% CI, 24.16%-50.24%). The peritoneal (hazard ratio [HR], 1.75; 95% CI, 1.10–2.79; P = 0.0189) and metastasis to two or more organs or sites (HR, 1.59; 95% CI, 1.05–2.43; P = 0.0304) were PRS-independent adverse prognostic factors.ConclusionThe prognosis of patients with peritoneum and multiple organs or sites recurred was poor. This study suggests early monitoring of peritoneal and multiple organ or site recurrence after surgery. This part of patients should receive comprehensive treatment as early as possible to improve their prognosis.

Effect of local treatment in patients with oligo-recurrence after surgery of distal bile duct cancer: A bi-institutional study.

Distal extrahepatic bile duct (EHBD) cancer is highly recurrent. More than 50% of patients suffer from disease relapse after curative resection. Some patients present with oligo-recurrence which could be a single loco-regional mass or lesions limited to a single solid organ. The aim of this study was to examine the effect of local control (surgical resection or radiofrequency ablation) on survival outcomes in patients with oligo-recurrent distal EHBD cancer. Data of 1219 patients who underwent surgery for distal EHBD cancer from 2000 to 2018 were retrospectively reviewed. Clinicopathological characteristics and survival outcomes of patients with recurrence were investigated. Post-recurrence survival (PRS) was analyzed according to modalities of re-treatment (local treatment or systemic therapy alone). Among 654 patients with recurrence, 90 patients who had oligo-recurrence showed better recurrence-free and overall survival than patients with non-oligo-recurrent disease. Lymph node ratio and perineural invasion at initial pathology, timing of recurrence, and platelet-to-lymphocyte ratio at recurrence were independent risk factors for PRS in the oligo-recurrent group. Patients with local treatment for oligo-recurrence had better 3- and 5-year PRS than those with systemic treatment alone (38.3% vs. 14.1%, p=0.04; 28.3% vs. 7.1%, p=0.04, respectively). Recurrence within 24 months after initial surgery was the only significant factor for PRS in the local treatment group. In patients with oligo-recurrence after resection of distal EHBD cancer, post-recurrence local treatment could improve survival outcomes, particularly for those with recurrence more than 2 years after initial resection.

Prognostic influences of B-cell lymphoma 2-positive expression on late recurrence in breast cancer.

B-cell lymphoma 2 (BCL2) has an antiapoptotic role, however, has resulted in it being a powerful favorable prognostic factor in breast cancer. Several studies revealed BCL2 is strongly associated with a lower rate of early recurrence after initial treatment in breast cancer patients, but study of a prolonged effect after 5 years is lacking. We investigated BCL2 as a prognostic factor in breast cancer in comparison to early and late recurrence. We retrieved data from 2,198 patients with primary breast cancer who underwent surgical treatment and adjuvant treatment at the breast cancer center between 2005 and 2015. Each molecular subtype was classified, and Ki-67 and BCL2 were also assessed by immunohistochemistry. BCL2 and the association between molecular subtypes were assessed in early and late recurrences, respectively. Five-year postrecurrence survival and BCL2 were also assessed. The BCL2-positive group was associated with favorable clinicopathologic characteristics. The time to recurrence was significantly longer in the BCL2-positive group (P = 0.035). Late recurrence after 5 years was higher in the BCL2-positive group (P = 0.029). In multivariate survival analysis, tumor size and BCL2-positive expression were the only independent prognostic factors for late recurrence (P = 0.004). In the patients with recurrence, 5-year postrecurrence survival was significantly higher in the BCL2-positive group (P < 0.001). Our result showed that prognosis was better in BCL2-positive patients compared to BCL2-negative patients at late recurrence. We suggested that BCL2 expression could be used as a marker to help determine additional adjuvant therapy or extended hormone therapy in hormone-dependent breast cancer.

Hepatectomy is associated with improved oncologic outcomes in recurrent colorectal liver metastases: A propensity-matched analysis

BackgroundFollowing resection of colorectal liver metastasis, most patients have disease recurrence, most commonly intrahepatic. Although the role of resection in colorectal liver metastasis is well-established, there have been limited investigations assessing the benefit of repeat hepatic resection compared with systemic treatment alone for intrahepatic recurrence. MethodsA retrospective single-institution cohort study of patients with recurrent colorectal liver metastasis following curative-intent hepatectomy was performed from 2003 to 2019. The oncologic outcomes, including post-recurrence overall survival, were evaluated using Kaplan-Meier and Cox proportional hazards modeling. Patients undergoing repeat hepatic resection were propensity-matched with patients receiving systemic treatment alone based on relevant clinicopathologic variables. ResultsThere were 338 patients treated with hepatic resection for colorectal liver metastasis over the study period. Liver recurrence was observed in 147 (43%) patients at a median time of 10 months from prior resection, with a median post-recurrence overall survival of 29 months. There were 37 patients managed with repeat hepatic resection; 33 (89%) received perioperative chemotherapy. On propensity matching, there were no significant clinicopathologic differences between 37 patients having repeat hepatic resection and 37 patients treated with systemic treatment alone. Repeat hepatic resection was independently associated with improved 5-year post-recurrence overall survival compared with systemic treatment alone (median overall survival 41 vs 35 months, 5-year overall survival 19% vs 3%, P = .048). ConclusionDisease characteristics of patients with intrahepatic recurrence of colorectal liver metastasis, specifically the number of liver lesions and size of the largest lesion, are most predictive of survival and response to systemic therapy. Patients who recur with oligometastatic liver disease experience improved outcomes and derive benefit from curative-intent repeat hepatic resection with integrated perioperative systemic therapy.

The value of completion residual lung resection in ipsilateral recurrent non-small cell lung cancer.

Recurrence is one of the most important challenges to manage lung cancer. Selected patients might be candidates for resection. This study assessed the outcomes and hazard factors of patients after completion of lung resection for recurrence, focusing specifically on postrecurrence survival (PRS) and overall survival (OS) after surgery. This retrospective study enrolled 63 patients who underwent complete pulmonary resection for recurrence between January 2015 and December 2018. Inclusion criteria include potentially curative first resection for primary lung cancer, histologically proven recurrent or new malignancy, and complete pathological report after both operations. PRS and OS were assessed and the influence of patient and treatment features on these endpoints was evaluated. Most of the patients recurred at stage IIIA, and nearly three-fourth received complete pneumonectomy. The overall 2- and 5-year survival rates were 95% and 75%, whereas the overall 2- and 5-year postrecurrence survival rates were 55% and 36%, respectively. No patient died within 30 or 90 days after completion of residual lung resection, and no serious complications occurred during follow-up. Upon selection of clinically important variables by the Cox proportional hazards regression model, the r-stage [hazard ratio (HR), 3.35; 95% CI, 1.11-10.10; P = 0.03] and stage of primary tumor (HR, 6.26; 95% CI, 2.00-19.55; P < 0.01) were hazard factors for PRS and OS respectively. Complete pulmonary resection is an acceptable option in selected patients with recurrent lung cancer after surgery. The patients with r-stage earlier than IIIA may benefit from completion pulmonary resection but not IIIB. Completion pneumonectomy failed to significantly prolong the OS. The OS in the enrolled cases was mainly affected by the p-TNM stage assessed by the first resection for primary lung cancer.

Ten-Year Outcomes of Liver Transplant and Downstaging for Hepatocellular Carcinoma

National guidelines on transplant selection have adopted successful downstaging to within Milan criteria (MC) as a viable option for the treatment of hepatocellular carcinoma (HCC) before liver transplant (LT). Recurrence of HCC after LT carries a poor prognosis, and treatment modalities remain challenging. To establish the 10-year outcomes of patients with HCC after LT in a large, multicenter US study based on individual data; provide robust data on the long-term role of downstaging; and evaluate the association of treatment modalities with postrecurrence survival. In this cohort study, a retrospective, multicenter analysis of prospectively collected data was conducted for 2645 adults who had undergone LT for HCC at 5 US academic centers between January 2001 and December 2015. The analysis was performed from May 2019 through June 2021. Outcomes of 341 patients whose disease was downstaged to within MC were compared with those in 2122 patients whose disease was always within MC and 182 patients whose disease was not downstaged. The associations of tumor and treatment factors on postrecurrence survival were analyzed using Cox proportional hazards regression and multivariable logistic regression models. The primary outcome was overall survival for the whole cohort and according to downstaging status. Secondary outcomes were time to recurrence, recurrence-free survival, and recurrence after specific post-LT therapies. Of the 2645 patients studied, the median age was 59.9 years (IQR, 54.7-64.7 years). The majority of the patients were men (2028 [76.7%] vs 617 [23.3%] women). The 10-year post-LT survival and recurrence rates were, respectively, 52.1% and 20.6% among those whose disease was downstaged; 61.5% and 13.3% in those always within MC; and 43.3% and 41.1% in those whose disease was not downstaged. Independent variables associated with downstaging failure were tumor size greater than 7 cm at diagnosis (OR, 2.62; 95% CI, 1.20-5.75; P = .02), more than 3 tumors at diagnosis (OR, 2.34; 95% CI, 1.22-4.50; P = .01), and α-fetoprotein response of at least 20 ng/mL with less than 50% improvement from maximum α-fetoprotein before LT (OR, 1.99; 95% CI, 1.14-3.46; P = .02). Surgically treated patients with recurrent HCC differed in clinicopathologic characteristics and had improved 5-year postrecurrence survival rates (31.6% vs 7.3%; P < .001). In a large, multicenter cohort of patients with HCC successfully downstaged to within MC, 10-year post-LT outcomes were excellent, validating national downstaging policies and showing a clear utility benefit for LT prioritization decision making. Surgical management of HCC recurrence after LT was associated with improved survival in well-selected patients and should be pursued, if feasible.

Prognostic factors for post-recurrence survival among patients with locally advanced cervical cancer who underwent definitive concurrent chemoradiation.

BackgroundThe prognostic factors affecting post-recurrence survival (PRS) in patients with locally advanced cervical cancer (LACC) who receive concurrent chemoradiation (CCRT) are not well established. This study aimed to assess the prognostic factors for PRS in patients with recurrent LACC who underwent CCRT as the primary treatment.Materials and methodsWe retrospectively reviewed the medical records of patients with a first recurrence of cervical cancer (stage IB2–IVA), who were initially treated with CCRT and completed the planned radiotherapy from 2002 to 2018. Multivariate analysis of independent factors for PRS was performed with the Cox proportional-hazards model.ResultsOf 1,658 patients with LACC primarily treated with CCRT, 424 (25.6%) had recurrence, with 142, 125, and 157 patients having locoregional, distant, and combined recurrence, respectively. Approximately 75% of recurrence cases were detected within 2 years after completed treatment, and 81.8% of cases demonstrated symptoms at recurrence diagnosis. The median PRS was 8.4 months, and the 1- and 5-year PRS rates were 36.0% and 5.3%, respectively. Multivariate analysis found that the recurrence-free interval (RFI) (p < 0.001), recurrence pattern (p < 0.001), white blood cell count (p < 0.001), and treatment at recurrence (p < 0.001) were independent prognostic factors for PRS.ConclusionThe prognosis of recurrent LACC initially treated with CCRT was notably poor. RFI, recurrence pattern, white blood cell count, and treatment at recurrence were independent prognostic factors for PRS.

Impact of the initial site of metastases on post-recurrence survival for neuroendocrine cervical cancer

ObjectiveTo summarize the risk factors and emphasize the prognostic importance of the site of recurrent neuroendocrine cervical cancer (NECC).MethodsWe enrolled 88 patients who developed recurrence after radical surgery for pathological stage I–IVa primary NECC between January 2003 and 30 December 2020 and classified these cases into 7 groups based on the initial recurrence. The risk factors for post-recurrence survival (PRS) were analyzed by Kaplan–Meier and Cox regression methods.ResultsAmong 88 NECC patients, nearly all patients (95.50%) experienced progression within 3 years. The time to progression was significantly longer in patients with lung recurrence than in patients without lung recurrence (p = 0.008). After the first recurrence, the median follow-up was 11.1 months (range 2.37–65.50 months), and the 5-year PRS was only 20.6%. The depth of invasion in the primary surgery, number of recurrent sites, abdominal organ recurrence were correlated with PRS by univariate analysis. Multivariate analyses revealed that the number of recurrent sites (p = 0.025) and abdominal organ recurrence (p = 0.031) were independent prognostic factors. Notably, the combination of immune checkpoint inhibitors and chemotherapy, with or without surgery, showed a 43.8% objective response rate in recurrent NECC.ConclusionPatients with abdominal organ recurrence need more sophisticated therapy. The combination of immune therapy and chemotherapy might be an opportunity for recurrent NECC.

Post-recurrence survival analysis in patients with oligo-recurrence after curative esophagectomy

BackgroundRecurrent esophageal cancer is associated with dismal prognosis. There is no consensus about the role of surgical treatments in patients with limited recurrences. This study aimed to evaluate the role of surgical resection in patients with resectable recurrences after curative esophagectomy and to identify their prognostic factors.MethodsWe retrospectively reviewed patients with recurrent esophageal cancer after curative esophagectomy between 2004 and 2017 and included those with oligo-recurrence that was amenable for surgical intent. The prognostic factors of overall survival (OS) and post-recurrence survival (PRS), as well as the survival impact of surgical resection, were analyzed.ResultsAmong 654 patients after curative esophagectomies reviewed, 284 (43.4%) had disease recurrences. The recurrences were found resectable in 63 (9.6%) patients, and 30 (4.6%) patients received surgery. The significant prognostic factors of PRS with poor outcome included mediastinum lymph node (LN) recurrence and pathologic T3 stage. In patients with and without surgical resection for recurrence cancer, the 3-year OS rates were 65.6 and 47.6% (p = 0.108), while the 3-year PRS rates were 42.9 and 23.5% (p = 0.100). In the subgroup analysis, surgery for resectable recurrence, compared with non-surgery, could achieve better PRS for patients without any comorbidities (hazard ratio 0.36, 95% CI: 0.14 to 0.94, p = 0.038).ConclusionsMediastinum LN recurrence or pathologic T3 was associated with worse OS and PRS in patients with oligo-recurrences after curative esophagectomies. No definite survival benefit was noted in patients undergoing surgery for resectable recurrence, except in those without comorbidities.

Evaluation of peripheral nodal recurrence in patients with endometrial cancer

Objective:To evaluate the clinico-pathological patient features, prognostic factors, treatment options and outcomes of peripheral nodal recurrence (PNR) of endometrial cancer (EC).Material and Methods:The data of nine patients with PNR of EC from two institutions were reviewed. The electronic literature was reviewed from 1972 to May 2018 to identify articles about PNR in EC. Finally, 42 cases were evaluated.Results:Nineteen (45.2%) patients were initially diagnosed with either stage I or II disease, whereas 20 (47.7%) patients had stage III or IV disease while the stages were not reported in three (7.1%). PNR developed as the first recurrence in 40 (95.2%) patients and as the second recurrence in 2 (4.8%) patients. Isolated PNR appeared in 35 (83.3%). Seven (16.7%) had PNR coexisting with multiple other sites of tumoral involvement. In the entire cohort, the 5-year and 10-year post-recurrence survival (PRS) were both 78%. Only the presence of distant hematogenous metastasis concurrent with PNR was significantly related to poor PRS (p=0.005). Among patients with isolated PNR, those who had surgery had 30% greater 5-year PRS than those treated without surgery, but this difference was not significant (80% vs 50%; p>0.05).Conclusion:A concurrent distant hematogenous metastasis was the only factor related to poor survival. A wide range of therapies exists for PNR but none of the therapies appear to be more advantageous than another. However, surgery as a component of treatment can render a survival advantage for patients who have isolated PNR.

Risk Assessment for Loss-of-Exercise Capacity After Lung Cancer Surgery: Current Advances in Surgery and Systemic Treatment.

Considering advances in current post-recurrence treatment, we examined the prognostic significance of the number of risk factors for loss-of-exercise capacity (LEC) after lung cancer surgery, which were identified by our previous prospective observational study. Risk factors for LEC were defined as a short baseline 6-min walk distance (<400m), older age (≥75years), and low predicted postoperative diffusing capacity for carbon monoxide (<60%). Patients were classified as Risk 0/I/II/III according to the number of risk factors. The survival data were retrospectively analyzed. Between 2014 and 2017, 564 patients (n = 307, 193, 57, 7; Risk 0/I/II/III) who underwent lung cancer surgery were included in the study. The number of risk factors was associated with smoking status, predicted postoperative forced expiratory volume in 1s, histology, pathological stage, and adjuvant therapy. In a multivariate Cox regression analysis, compared to Risk 0, Risk I/II/III showed significant associations with overall survival (hazard ratios: 1.92, 3.35, 9.21; 95% confidence interval: 1.27-2.92, 2.01-5.58, 3.64-23.35; Risk I/II/III, respectively). In 141 patients with recurrence, molecular targeted therapies (MTTs) or immune checkpoint inhibitors (ICIs) were included in 58%, 47%, 32%, and 0% (Risk 0/I/II/III) during the course of treatment. In patients with MTT/ICI treatment, the estimated 1-year and 3-year post-recurrence survival rates were 88% and 58%, respectively. Risk classification for LEC was associated with survival after lung cancer surgery, as well as post-recurrence treatment. The concept of physical performance-preserving surgery may contribute to improving the outcomes of current lung cancer treatment.

Long-Term Outcomes of Breast Cancer Patients Who Underwent Selective Neck Dissection for Metachronous Isolated Supraclavicular Nodal Metastasis

Simple SummaryVery limited studies so far have analyzed the long-term oncologic outcomes of breast cancer patients that developed metachronous isolated supraclavicular nodal metastasis (miSLNM) with no available treatment strategy for the critical issue. The study enrolled 139 miSLNM patients; 61 patients underwent selective neck dissection. In median follow-up of 73.1 months, significantly better 5-year overall survival rate was found in the neck dissection group compared to the no-dissection group (68.9% vs. 57.7%, respectively; HR, 1.77 (1.22–2.55), p = 0.003). The findings suggest surgery for miSLNM should be integrated into multimodal therapy of miSLNM, and the restaging of miSLNM as rN3c rather than M1 disease if detected earlier.We retrospectively enrolled 139 patients who developed metachronous isolated supraclavicular lymph node metastasis (miSLNM) from 8129 consecutive patients who underwent primary surgery between 1990 and 2008 at a single medical center. The median age was 47 years. The median follow-up time from date of primary tumor surgery was 73.1 months, and the median time to the date of neck relapse was 43.9 months in this study. Sixty-one (43.9%) patients underwent selective neck dissection (SND). The 5-year distant metastasis-free survival (DMFS), post-recurrence survival, and overall survival (OS) rates in the SND group were 31.1%, 40.3%, and 68.9%, respectively, whereas those of the no-SND group were 9.7%, 32.9%, and 57.7%, respectively (p = 0.001). No SND and time interval from primary tumor surgery to neck relapse ≤24 months were the only significant risk factors in the multivariate analysis of DMFS (hazard ratio (HR), 1.77; 95% confidence interval (CI), 1.23–2.56; p = 0.002 and HR, 1.76, 95% CI, 1.23–2.52; p = 0.002, respectively) and OS (HR, 1.77; 95% CI, 1.22–2.55; p = 0.003 and HR, 3.54, 95% CI, 2.44–5.16; p < 0.0001, respectively). Multimodal therapy, including neck dissection, significantly improved the DMFS and OS of miSLNM. Survival improvement after miSLNM control by intensive surgical treatment suggests that miSLNM is not distant metastasis.

Long-Term Survivors after Upfront Resection for Pancreatic Ductal Adenocarcinoma: An Actual 5-Year Analysis of Disease-Specific and Post-Recurrence Survival.

Data on long-term actual survival in patients with surgically resected pancreatic ductal adenocarcinoma (PDAC) are limited. The aim of this study was to evaluate the actual 5-year disease-specific survival (DSS) and post-recurrence survival (PRS) in patients who underwent pancreatectomy for PDAC. Data from patients who underwent upfront surgical resection for PDAC between 2009 and 2014 were analyzed. Exclusion criteria included PDAC arising in the background of an intraductal papillary mucinous neoplasm and patients undergoing neoadjuvant therapy. All alive patients had a minimum follow-up of 60 months. Independent predictors of PRS, DSS, and survival >5 years were searched. Of the 176 patients included in this study, 48 (27%) were alive at 5years, but only 20 (11%) had no recurrence. Median PRS was 12months. In the 154 patients after disease recurrence, independent predictors of shorter PRS were total pancreatectomy, G3 tumors, early recurrence (<12months from surgery), and no treatment at recurrence. Median DSS was 36 months. Independent predictors of DSS were CA19-9 at diagnosis >200U/mL, total pancreatectomy, N+ status, G3 tumors and perineural invasion. Only the absence of perineural invasion was a favorable independent predictor of survival >5years. More than one-quarter of patients who underwent upfront surgery for PDAC were alive after 5years, although only 11% of the initial cohort were cancer-free. Long-term survival can also be achieved in tumors with more favorable biology in an upfront setting followed by adjuvant chemotherapy.
