Surgical intervention for lung cancer in patients aged 75 and above: potential associations with increased mortality rates—a single-center observational study

BackgroundLung cancer, which is diagnosed two to three times more frequently in patients over the age of 70, is a leading cause of cancer-specific mortality. Given the elevated risk of morbidity and mortality, surgical intervention may not always be the most appropriate primary treatment option. This study aims to evaluate specific risk factors associated with postoperative morbidity and mortality in elderly patients and to optimize patient selection therefore improving surgical outcomes.Patients and methodsThe study encompassed a cohort of 73 patients aged 75 and above who underwent surgical treatment for non-small cell lung cancer (NSCLC) at the Department of Thoracic Surgery of the P. Hertsen Moscow Oncological Research Institute between 2015 and 2021. All patients underwent preoperative evaluation, including PET/CT staging and functional assessment, carried out by a multidisciplinary team comprising thoracic surgeons, anesthesiologists, and other medical specialists.ResultsThe investigation revealed a postoperative mortality rate of 5.5% and a postoperative morbidity incidence of 16.4%, with occurrences of atrial fibrillation in 41.6%, persistent air leak in 33.3%, and pneumonia in 25% of complicated cases. At the one-year follow-up, 88% of patients remained free from relapse, whereas at three years, this rate stood at 66%. During the follow-up period, 16 patients (22%) passed away, with a median survival duration of 44 months. Survival rates at one year, three years, and five years were 71%, 66%, and 35%, respectively. Multivariate analysis disclosed several significant factors predicting a complex postoperative period, including stage IIIb (p = 0.023), pN1 (p = 0.049), pN2 (p = 0.030), and central location (p = 0.007). Additionally, overall survival was primarily influenced by a Charlson comorbidity index of 6 (p = 0.044), stage Ia2 (p = 0.033), and the necessity for thoracotomy (p = 0.045).ConclusionEach case of lung cancer in patients aged 75 and older necessitates an individualized approach. Given the higher mortality rate relative to younger patients, comprehensive risk assessment and preoperative management of underlying comorbidities are imperative, with the involvement of anesthesiologists, intensive care physicians, cardiologists, and other relevant specialists as needed.

CT morphological features and histogram parameters to predict micropapillary or solid components in stage IA lung adenocarcinoma.

This study aimed to construct prediction models based on computerized tomography (CT) signs, histogram and morphology features for the diagnosis of micropapillary or solid (MIP/SOL) components of stage IA lung adenocarcinoma (LUAC) and to evaluate the models' performance. This clinical retrospective study included image data of 376 patients with stage IA LUAC based on postoperative pathology, admitted to Putian First Hospital from January 2019 to June 2023. According to the presence of MIP/SOL components in postoperative pathology, patients were divided into MIP/SOL+ and MIP/SOL- groups. Cases with tumors ≤ 3cm and ≤ 2cm were separately analyzed. Each subgroup of patients was then randomly divided into a training set and a test set in a ratio of 7:3. The training set was used to build the prediction model, and the test set was used for internal validation. For tumors ≤ 3cm, ground-glass opacity (GGO) [odds ratio (OR) = 0.244; 95% confidence interval (CI): 0.103-0.569; p = 0.001], entropy (OR = 1.748; 95% CI: 1.213-2.577; p = 0.004), average CT value (OR = 1.002; 95% CI: 1.000-1.004; p = 0.002), and kurtosis (OR = 1.240; 95% CI: 1.023-1.513; p = 0.030) were independent predictors of MIP/SOL components of stage IA LUAC. The area under the ROC curve (AUC) of the nomogram prediction model for predicting MIP/SOL components was 0.816 (95% CI: 0.756-0.877) in the training set and 0.789 (95% CI: 0.689-0.889) in the test set. In contrast, for tumors ≤ 2cm, kurtosis was no longer an independent predictor. The nomogram prediction model had an AUC of 0.811 (95% CI: 0.731-0.891) in the training set and 0.833 (95% CI: 0.733-0.932) in the test set. For tumors ≤ 3cm and ≤ 2cm, GGO, average CT value, and entropy were the same independent influencing factors in predicting MIP/SOL components of stage IA LUAC. The nomogram prediction models have potential diagnostic value for identifying MIP/SOL components of early-stage LUAC.

Is fluorometric sentinel lymph node biopsy in endometrial cancer necessary?

In this study, we collected perioperative and postoperative follow-up data from patients with endometrial cancer (EC) at different stages to evaluate the role of sentinel lymph node biopsy (SLNB) in endometrial cancer surgery. A total of 186 endometrial cancer patients undergoing radical hysterectomy from January 2018 to April 2022 were retrospectively analyzed. Patients were classified into four groups. Group A comprised patients diagnosed with stage IA grade 1 and 2 endometrioid EC who underwent SLNB. Group B comprised patients with stage IA grade 1 and 2 endometrioid EC who did not undergo SLNB. Group C comprised patients with higher-grade endometrioid EC, wherein systematic lymph node dissection was performed based on SLNB results. Group D comprised patients with higher-grade endometrioid EC who did not undergo SLNB and instead underwent direct systematic lymph node dissection. Clinical, pathological data, and follow-up information for all patients were collected. In Group A and B, SLNB was performed on 36 out of 67 patients with IA stage 1 and 2 endometrial cancer, yielding a SLN positivity rate of 5.6%. There were no significant differences observed between the two groups regarding perioperative outcomes and postoperative follow-up. Conversely, among 119 patients with higher-grade endometrial cancer, 52 underwent SLNB, with 20 patients exhibiting SLN positivity, resulting in a SLN positivity rate of 38.4%. However, the decision to undergo SLNB did not yield significant differences in perioperative outcomes and postoperative follow-up among these patients. For stage IA grade 1 and 2 endometrioid EC, the incidence of lymph node positivity is low, omitting SLNB in this subpopulation is a feasible option. In other stages of endometrioid EC, there is no significant difference in perioperative and postoperative follow-up data between patients undergoing routine systematic lymphadenectomy and those undergoing systematic lymphadenectomy based on SLNB results. Therefore, if SLNB is not available, the standard procedure of PLND remains an option to obtain information about lymph node status, despite the surgical complications associated with this procedure.

Estimating the magnitude and healthcare costs of melanoma in situ and thin invasive melanoma overdiagnosis in Australia.

Research suggests a high proportion of melanoma in situ (MIS) may be overdiagnosed, potentially contributing to overtreatment, patient harm and inflated costs for individuals and healthcare systems. However, Australia-wide estimates of the magnitude of melanoma overdiagnosis are potentially outdated and there has been no estimation of the cost to the healthcare system. To estimate the magnitude and cost of overdiagnosed MIS and thin invasive melanomas in Australia. Using two different methods for calculating lifetime risk, we used routinely collected, national-level data to estimate overdiagnosed MIS and thin invasive melanomas (stage IA) in Australia in 2017 and 2021, separately for men and women. We multiplied the number of overdiagnosed melanomas by the estimated annual cost of a MIS or thin invasive melanoma to quantify the financial burden of melanoma overdiagnosis to the Australian healthcare system in the year following diagnosis. We estimated that between 67-70% of MIS were overdiagnosed in 2017, rising to 71-76% in 2021, contributing to between 19,829 (95%CI: 19,553-20,105) and 20,811 (95%CI: 20,528-21,094) overdiagnosed MIS. In 2021, the estimated costs in Australia ranged between $17.7 million (95%CI: $17.4-17.9 million) and $18.6 million (95%CI: $18.3-18.8 million). We estimated that 22-29% of thin invasive melanomas were overdiagnosed in 2017, rising to 28-34% in 2021, contributing to between 2,831 (95%CI: 2,726-2,935) and 3,168 (95%CI: 3,058-3,279) overdiagnosed thin invasive melanomas. In 2021, the estimated costs from thin invasive melanoma overdiagnoses ranged between $2.5 million (95%CI: $2.4-2.6 million) and $2.8 million (95%CI: $2.7-2.9 million). Melanoma overdiagnosis is a growing clinical and public health problem in Australia, producing significant economic costs in the year following overdiagnosis. Limiting melanoma overdiagnosis may prevent unnecessary healthcare resource use and improve financial sustainability within the Australian healthcare system.

Medical costs of lung cancer by stage, histology and first-line treatment modality in the Netherlands (2012–2021)

IntroductionLung cancer is a leading cause of mortality worldwide, with lung cancer treatment presenting a significant financial burden. The treatment landscape has recently shifted, seeing an increase in targeted- and immunotherapies. Such treatments are expensive, but estimates of the medical costs of the lung cancer treatment pathway largely predate their introduction. MethodsWe link medical expenditures of individuals resident in the Netherlands (n = 19.2 m) for 2013–2021 to tumour-level (n = 137,129, incident 2012–2021) Netherlands Cancer Registry data. We estimate lung cancer-attributable costs by phase of care (initial, continuing and terminal), stratified by cancer stage and histology, and observe trends in medical costs over time. ResultsWe estimate mean costs over the lung cancer treatment pathway to be €48,443 per patient. Total medical costs are highest in the initial phase, followed by the terminal and continuing phase. Monthly treatment for stage IV lung cancer is significantly more expensive than for early-stage disease (€8293 per month of initial care relative to €3228 for stage IA). Stage IV lung cancer has become significantly more expensive to treat 2018–2021 relative to 2013–2017, with monthly expenditures rising 55 % in initial care and 148 % in continuing care. Population-wide, we find €900.6 million spent on lung cancer care in 2021, €433 million more than in 2016, of which €307.3 million is attributed to per-patient expenditure trends. ConclusionsTreatment advances are quickly inflating medical costs for late-stage lung cancer. Policy makers should carefully evaluate the cost-effectiveness of novel treatments, and incorporate stage-specific treatment costs in evaluating interventions for early detection.

Association of albumin, neutrophil-lymphocyte ratio and lymphocytes with clinical stage in cervical cancer patients.

To determinate the association between of albumin, neutrophil-lymphocyte ratio and lymphocytes (NLR) with clinical stage in cervical cancers. Design a retrospective cross-sectional study of consecutive subjects diagnosed with cervical cancer for the first time. The Bethesda system was used for histological diagnosis and the subjects were stratified with the FIGO system, considering stages IA to IIB as localized; while, IIIA and IVB as advanced stages. Albumin, NLR and lymphocytes were evaluated as inflammatory biomarkers and the cut-off points generated by the ROC curves were albumin < 3mg/dL, NLR ≥ 2.0 and lymphocytes < 1.2 103/ul. The association was calculated by Odds Ratios (OR) with 95% confidence intervals. A total of 152 patients were analyzed, with mean age of 49.3 ± 14.0years. Epidermoid cancer was the most frequent in 70.6% and 51.3% were classified as advanced clinical stages. A bivariate analysis showed significant relationships between advanced clinical stages and albumin < 3mg/dL with OR 5.72 (CI95% 2.62-12.4; p < 0.001); for NLR ≥ 2.0 an OR 2.53 (CI95% 1.34-4.89; p = 0.005) and for lymphocytes < 1.2 103/ul of OR 3.39 (CI95% = 1.73-6.65; p < 0.001). Albumin levels < 3mg/dL, NLR ≥ 2.0 and lymphocytes < 1.2 103/ul, were associated with advanced stages in subjects with cervical cancer.

Survival and pulmonary function in stage IA non-small cell lung cancer after sublobar resection versuslobectomy: An updated meta-analysis.

Traditionally, lobectomy was standard for stage IA non-small-cell lung cancer (NSCLC). Recent RCTs suggest sublobar resection's comparable outcomes. Our meta-analysis, incorporating 30 studies (including fourRCTs), assessed sublobar resection's efficacy. Employing a random-effects model and I2 statistics for heterogeneity, we found sublobar resection reduced DFS (HR 1.31, p < 0.01) and OS (HR 1.27, p < 0.01) overall. However, RCT subgroup analysis showed no significant differences in DFS (p = 0.28) or OS (p = 0.62). Sublobar resection is a viable option for well-selected patients.

Stage IA papillary and chromophobe renal cell carcinoma: effectiveness of cryoablation and partial nephrectomy

ObjectivesTo evaluate the effectiveness of cryoablation compared to partial nephrectomy in patients with stage IA papillary and chromophobe renal cell carcinoma (pRCC; chRCC).Material and methodsThe 2004–2016 National Cancer Database was queried for adult patients with stage IA pRCC or chRCC treated with cryoablation or partial nephrectomy. Patients receiving systemic therapy or radiotherapy, as well as those with bilateral RCC or prior malignant disease were excluded. Overall survival (OS) was assessed using Kaplan–Meier plots and Cox proportional hazard regression models. Nearest neighbor propensity matching (1:1 cryoablation:partial nephrectomy, stratified for pRCC and chRCC) was used to account for potential confounders.ResultsA total of 11122 stage IA renal cell carcinoma patients were included (pRCC 8030; chRCC 3092). Cryoablation was performed in 607 (5.5%) patients, and partial nephrectomy in 10515 (94.5%) patients. A higher likelihood of cryoablation treatment was observed in older patients with non-private healthcare insurance, as well as in those with smaller diameter low-grade pRCC treated at non-academic centers in specific US geographic regions. After propensity score matching to account for confounders, there was no statistically significant difference in OS comparing cryoablation vs partial nephrectomy in patients with pRCC (HR = 1.3, 95% CI: 0.96–1.75, p = 0.09) and those with chRCC (HR = 1.38, 95% CI: 0.67–2.82, p = 0.38).ConclusionAfter accounting for confounders, cryoablation, and partial nephrectomy demonstrated comparable OS in patients with stage IA papillary and chromophobe RCC. Cryoablation is a reasonable treatment alternative to partial nephrectomy for these histological RCC subtypes when radiologically suspected or diagnosed after biopsy.Critical relevance statementCryoablation might be considered as an upfront treatment alternative to partial nephrectomy in patients with papillary and chromophobe stage IA renal cell carcinoma, as both treatment approaches yield comparable oncological outcomes.Key PointsThe utilization of cryoablation for stage IA papillary and chromophobe RCC increases.In the National Cancer Database, we found specific patterns of use of cryoablation.Cryoablation and partial nephrectomy demonstrate comparable outcomes after accounting for confounders.Graphical

Therapeutic effect of induction therapy including nab-paclitaxel followed by surgical resection for the patients with locally advanced non-small-cell lung cancer

BackgroundLung cancer is associated with a high mortality rate worldwide. Non-small-cell lung cancer (NSCLC) is a major subtype of lung cancer. Carboplatin (CBDCA) plus nab-paclitaxel (PTX) has become a standard treatment for advanced unresectable NSCLC. However, treatment with nab-PTX has not been established as a standard therapy for resectable locally advanced (LA)-NSCLC.MethodsWe conducted a comprehensive study involving consecutive patients with locally advanced NSCLC who underwent induction therapy including nab-PTX followed by surgical resection. Fifteen patients with locally advanced NSCLC underwent induction therapy including nab-PTX followed by surgical resection. Concurrent chemoradiotherapy (CRT) consisted of weekly administration of nab-PTX (50 mg/m2) plus CBDCA (area under the plasma concentration time curve (AUC) 2) and thoracic radiotherapy (50 Gy/25 fractions).ResultsThe clinical stages were as follows: IIB (n =1), IIIA (n =12), and IIIC (n =2). Downstaging was observed in 73% (11/15) of patients on comparison with the clinical stage before concurrent CRT. Adverse drug reactions were observed in seven patients. Complete resection was performed in all patients. The re-evaluated pathological stage after pretreatment was diagnosed as stage 0 in three patients, stage IA1 in six, stage IA2 in one, and stage IIIA in five. The pathological effects of previous therapy were as follows: Ef3 (n =3), Ef2 (n =9), and Ef1a (n =3).ConclusionThe therapeutic effect of induction therapy including nab-PTX was promising. Induction CRT, including nab-PTX, followed by resection, may be a viable alternative treatment option for locally advanced NSCLC.

Clinical, Imaging, and Pathological-Molecular Characteristics Associated with Stage IA Invasive Lung Adenocarcinoma Recurrence After Sub-lobar Resection

Rationale and ObjectivesThis study aimed to investigate the association of clinical, imaging, and pathological-molecular characteristics with the prediction of patient prognosis with stage IA invasive lung adenocarcinoma (ILADC) after sub-lobar resection. Materials and MethodsThis study assessed 360 patients, including 91 and 269 with and without recurrence 3 years postoperativel, respectively, with stage IA ILADC undergoing preoperative chest computed tomography (CT) scans and subsequent sub-lobar resection at our institution. Their clinical and CT features and histological subtypes and gene mutation status were compared. Binary logistic regression analysis was conducted to identify the independent risk factors for recurrence. An external validation cohort included 113 patients, used to test the model’s efficiency. ResultsFor clinical features, old age, male gender, smokers, and high age-adjusted Charlson comorbidity index (ACCI) were frequently observed in patients with recurrence than those without (all p < 0.05). For CT features, large tumor size, solid-predominant density, spiculation, peripheral fibrosis, type II pleural tag, and pleural adhesion were more common in recurrent patients than non-recurrent ones (all p < 0.05). The regression model revealed old age, large tumor size, solid-predominant density, spiculation, type II pleural tag, and pleural adhesion as independent risk factors for recurrence, with an area under the curve (AUC) of 0.942. The external validation cohort obtained an AUC of 0.958. For phological-molecular features, miropapillary/solid-predominant growth pattern, KRAS, ALK, and NRAS mutation or fusion were more ccommon in the recurrent group, whereas EGFR mutation was more frequent in the non-recurrent group (all p < 0.05). ConclusionClinical and CT features help predict the prognosis of patients with stage IA ILADC after sub-lobar resection and decide for individualized treatment. Moreover, patients with different prognosis demonstrated different pathological-molecular features.

Simple Versus Radical Hysterectomy in Women With Low-Risk Cervical Cancer

(Abstracted from N Engl J Med 2024;390:9) Radical hysterectomy is the standard-of-care treatment for early-stage cervical cancer; however, observational studies suggest no survival benefit between patients who undergo radical hysterectomy versus simple hysterectomy for stage IA2 cervical cancer. Additionally, 2 recent large studies have raised the question of whether simple hysterectomy compares favorably overall with radical hysterectomy in stage IA2 or IB1 disease with mixed evidence.

Adjuvant 5-fluorouracil and portal vein infusion chemotherapy followed by gemcitabine for pancreatic cancer.

Although adjuvant gemcitabine (GEM) monotherapy improves the overall survival (OS) of patients with resected pancreatic cancer, its efficacy requires further improvement. This multicenter, phase II study investigated the efficacy of adjuvant portal vein infusion (PVI) chemotherapy followed by GEM therapy in patients with resected pancreatic cancer. 5-fluorouracil (250 mg/day) and heparin (2000 IU/day) PVI chemotherapy were combined with systemic administration of mitomycin C (4 mg; days 6, 13, 20, and 27) and cisplatin (10 mg; days 7, 14, 21, and 28) for 4 weeks (PI4W), followed by GEM (1000 mg/m2; days 1, 8, and 15 every 4 weeks for 6 months). The primary endpoint was relapse-free survival (RFS) and the secondary endpoints were OS and treatment completion. Between November 2010 and August 2013, 53 patients who underwent complete resection were enrolled, including 30, 20, and 3 patients who underwent pancreaticoduodenectomies and distal and total pancreatectomies, respectively. In total, 51 (96.2%) patients underwent R0 resection, of whom 3, 2, 12, 35, 0, and 1 had stages IA, IB, IIA, IIB, III, and IV cancer, respectively, and 47 (88.7%) patients completed PI4W. The median RFS was 22.0 months (1-, 3-, 5, and 10 years RFS: 64.9%, 38.1%, 38.1%, and 38.1%, respectively), whereas the median OS was 32.0 months (1-, 3-, 5, and 10 years OS:86.6%, 47.2%, 44.4%, and 44.4%, respectively). Treatment with PI4W followed by GEM for 6 months after surgery may be beneficial in patients undergoing curative resection of pancreatic cancer.

Treatment Patterns and Surgical Outcomes of Stage IA1 Cervical Carcinoma

OBJECTIVE The primary objective was to determine the 5-year overall survival rate and 5-year disease-free survival rate of patients with CACx 1A1 treated at Chiang Mai University Hospital and the secondary objective was to describe treatment modalities as well as their associated complications. METHODS Patients with stage IA1 cervical cancer diagnosed from January 2001 to June 2018 at Chiang Mai University Hospital were retrospectively reviewed. Inclusion criteria included previously untreated patients diagnosed with stage IA1 cervical cancer (2018 FIGO staging system). Exclusion criteria were patients with recurrent cervical cancer, other gynecologic malignancies, and those in a pregnant state. The analysis included treatment patterns, surgical types, and clinicopathologic variables, i.e., nodal metastasis, parametrial involvement, positive surgical margins, deep stromal invasion (DSI), lymph-vascular space invasion (LVSI), adjuvant treatment, 5-year disease-free survival, and 5-year overall survival. All pathologic slides were reviewed by gynecologic pathologists. The Kruskal-Wallis test, Fisher’s exact test, the Kaplan-Meier method and log-rank test were used for statistical analysis. RESULTS Of the 184 patients included in this study, simple hysterectomy was the most common treatment (57.3%), followed by modified radical hysterectomy (MRH) and radical hysterectomy (RH) (27.6% and 9.7% respectively). Conization and radiation were chosen in a few cases. At the median follow up time of 40.8 months, the 5-year disease free survival rate was 99.1% and the 5-year overall survival rate was 95.0%. Pelvic lymph node dissection was done in 62 cases (33.7%), but only one case (0.54%) had pelvic lymph node metastasis. CONCLUSIONS The surgical and survival outcomes for women with stage IA1 cervical cancer are excellent. They can be effectively treated with less radical interventions such as simple hysterectomy and conization. Lymph node metastasis is rare at this stage (0.54%); therefore, lympha-denectomy may possibly be omitted. KEYWORDS cervical cancer, IA1, treatment outcome

Utility of PET for Nodal Staging in Subsolid Clinical Stage IA (T1 N0) Lung Adenocarcinoma

BackgroundPositron emission tomography (PET) is the standard of care for non-small cell lung cancer (NSCLC) clinical staging, but it may have limited utility in evaluating subsolid lung adenocarcinomas that can have relatively indolent behavior without hypermetabolic activity. MethodsThe sensitivity and specificity of PET for determining pathologic lymph node status and disease-free survival were assessed in patients operated on for cT1 N0 subsolid lung adenocarcinoma from January 2006 to June 2022 (at Stanford University School of Medicine, Stanford, CA). Patients with clinical or pathologic tumor size >30 mm, hilar or mediastinal lymph node size >1cm, and purely solid tumors were excluded. ResultsPET was available in 498 of 534 (93.2%) patients and more often was used in older patients with larger and more solid tumors. The overall pathologic lymph node–positive rate was 8.4% (45 of 534). PET specificity was 95.1%, but sensitivity was only 20.0%. A tumor diameter of 18.5 mm and a solid component percentage of 62.5% had the maximum predictive accuracy for pathologic lymph node positivity, with a 0% and 1.5% rate of pathologic and PET lymph node positivity, respectively, for tumors with values lower than those thresholds. There was no significant difference in 5-year disease-free survival between individuals who did and did not undergo PET scanning (76.6% vs 96.8%; P = .07). Conversely, 134 (26.9%) patients who underwent PET scanning had 171 incidentally detected hypermetabolic lesions unrelated to lung cancer, with only 13 of 134 (9.7%) patients identified as having non-NSCLC premalignant or malignant conditions requiring further therapy. ConclusionsPET scan use for subsolid lung adenocarcinoma has high specificity but limited sensitivity for predicting pathologic lymph node positivity. PET also has no association with disease-free survival and often detects clinically unimportant findings rather than changing lung cancer management, particularly for patients with smaller and less solid tumors.

Psychiatric Comorbidities and Survival After Lobectomy for Stage I Non-Small Cell Lung Cancer

BackgroundThe association between psychiatric comorbidities (PCs) and long-term survival after lobectomy for early-stage non-small cell lung cancer is unknown. We sought to investigate this relationship using the Surveillance, Epidemiology, & End-Results (SEER)-Medicare registry. MethodsData for all patients in the SEER-Medicare registry who underwent lobectomy for stage I non-small cell lung cancer from 2007 to 2014 were included. Those older than 80 years at time of diagnosis, with multiple cancers, or histology other than adenocarcinoma or squamous cell carcinoma were excluded. Patients diagnosed with depression, anxiety, bipolar disorder, schizophrenia, other (non-schizophrenic) psychotic disorders, unspecified mood disorder, attention-deficit/hyperactivity disorder, alcohol use disorder, or substance use disorder prior to lung cancer diagnosis were considered to have a PC. Survival of patients with PC was compared to controls using univariable and multivariable analysis adjusting for age, sex, race, stage (IA/IB), histology, surgical approach, and Charlson Comorbidity Index. ResultsOf 5516 patients, 1369 (24.8%) had PCs. Patients with PCs were more likely to be younger (P < .001), female (P < .001), white (P < .001), and have stage IA cancer (P < .001). PC was associated with shorter survival (median, 2478 vs 2820 days; P = .002). Multivariable analysis retained PC in the final model, with a hazard ratio of 1.10 (P < .001). Subgroup analysis revealed that this survival difference was driven by differences in survival of patients with schizophrenia (P < .001) and alcohol use disorder (P = .006). ConclusionsSelect psychiatric comorbidities are associated with reduced survival after lobectomy for early-stage non-small cell lung cancer.

Optimizing Organ-Preservation Strategies Through Chemotherapy-Based Selection in Esophageal Squamous Cell Carcinoma: Results From the CROC Multi-Institutional Phase 2 Clinical Trial

PurposeThis study aimed to assess the viability of definitive chemoradiotherapy (dCRT) as an organ-preservation strategy for remarkable responders who were downstaged to stage IA after receiving induction chemotherapy for resectable esophageal squamous cell carcinoma (ESCC). Methods and MaterialsChemotherapy-naïve patients with resectable ESCC (stage IB–III, UICC, International Cancer Control 7th edition) were eligible for the study. All patients received three cycles of DCF therapy (docetaxel 75 mg/m2 on day 1, cisplatin 75 mg/m2 on day 1, and 5-fluorouracil [5-FU] 750 mg/m2 on days 1–5, repeated every three weeks). A remarkable response was defined as a reduction of the tumor to T1, metastatic lymph nodes smaller than 1 cm on the short axis, and downstaging to stage IA after three cycles of DCF therapy. Remarkable responders then underwent dCRT, which included two courses of cisplatin 75 mg/m2 and 5-FU 1000 mg/m2 on days 1–4, repeated every four weeks, along with 50.4 Gy of concurrent radiotherapy. The primary endpoint was 1-year progression-free survival (PFS) in remarkable responders following DCF therapy and subsequent dCRT. Secondary endpoints included 3-year overall survival (OS) and esophagectomy-free survival (EFS). ResultsOf the 92 patients registered, 90 were analyzed. A remarkable response to three courses of DCF therapy was observed in 58.4% of patients. Among these responders, 89.8% achieved a complete response after dCRT. During the median follow-up period of 33 months (range: 1–85 months), the 1-year PFS was 89.8% (95% confidence interval = 77.2%–95.6%, primary endpoint), and the 3-year OS was 83.7%. The 3-year OS and EFS rates in the analysis group were 74.1% and 45.3%, respectively. An 18F-fluorodeoxyglucose-positron emission tomography response after two courses of DCF therapy was significantly associated with OS (p = 0.0049). ConclusionsIn patients with resectable ESCC, dCRT for remarkable responders downstaging to stage IA after induction chemotherapy with three courses of DCF therapy is a feasible treatment option and provides an optimizing organ-preservation strategy of chemotherapy-based selection.

On the Way to Curing Advanced-Stage Mycosis Fungoides/Sézary Syndrome

Advanced-stage mycosis fungoides (MF) and Sézary syndrome (SS) have poor prognosis with median survivals of less than 5 years. Although a variety of treatments are approved for MF/SS patients, durable complete remissions (CR) are rare. Advanced-stage MF or SS patients who achieved CR and maintained in CR or stage IA for more than 10 years were identified by a retrospective search of the principal investigator's database. Of 2266 patients diagnosed with MF or SS, 23 patients with advanced-stage MF/SS (6 IIB, 1 IIIB, 5 IVA1, 3 IVA2, 8 IVB) who achieved CR and maintained in CR or stage IA for ≥ 10 years were identified. As final/curative treatment, 11 patients underwent allogeneic stem cell transplantation (SCT). Most patients presented at young age, underwent SCT with reduced intensity conditioning regimen, had matched related donors, and controllable post-transplant graft versus host disease. Eleven patients were treated with TSEB as part of combined modality protocol in 2 patients and debulking therapy before allogeneic SCT in 9 patients. Five stage IIB patients achieved CR with radiotherapy. Four patients with blood involvement were treated with extracorporeal photopheresis (ECP) in combination with long-term antibiotics and immunomodulatory agents. Long-term antibiotics were given to 14 patients. TSEB followed by allogeneic SCT, radiotherapy, ECP plus long-term antibiotics and immunomodulatory agents were the most common curative/final treatments found in our patients. We are reporting the details of our long-term complete responders' treatment course in the hopes of obtaining more cure responses in the future.
