Case report: prolonged durable clinical benefit and low toxicity from combination endocrine therapy in a patient with recurrent endometrial carcinoma

BackgroundEndometrial carcinoma is the most common gynecologic cancer, with increasing incidence and mortality. Combination endocrine therapy comprised of tamoxifen and progestational agents has demonstrated promising results in treating recurrent disease. This case report describes the prolonged clinical benefit of treatment with tamoxifen and megestrol acetate in a woman with recurrent, metastatic endometrial endometrioid carcinoma positive for estrogen (ER) and progesterone receptors (PR).CaseA 71-year-old gravida 1 para 1 woman presented with postmenopausal bleeding and vaginal discharge. Pelvic ultrasound and magnetic resonance imaging confirmed a 4.7 cm endometrial mass. The patient underwent a total laparoscopic hysterectomy, bilateral salpingo-oophorectomy, pelvic and para-aortic lymphadenectomy, and cystoscopy; pathology revealed a FIGO stage IA grade 1 ER/PR-positive endometroid endometrial adenocarcinoma. She continued under active surveillance for approximately 42 months until she experienced bone metastases in her pelvis, for which she received radiation therapy. Five months later, pulmonary metastases were detected, and she received six cycles of carboplatin and paclitaxel. She then started megestrol acetate and tamoxifen and has remained clinically stable with minimal side effects and reasonable quality of life for approximately 57 months.ConclusionOur case suggests that combination endocrine therapy has the potential to provide substantial long-term clinical benefit in women with recurrent endometrial cancer and bone metastases, despite multiple prior treatments, allowing patients to experience stable disease and quality of life. In patients with recurrent endometrioid, ER/PR-positive disease, endocrine therapy alone or in combination with other targeted therapies are regimens that may be considered due to their low overall toxicity.

Mapping sentinel lymph nodes in early-stage ovarian cancer (MELISA) trial - a further step towards lymphadenectomy replacement

ObjectiveSistematic pelvic and para-aortic lymphadenectomy is part of the staging surgery for early-stage epithelial ovarian cancer, with no therapeutic value. The Mapping Sentinel Lymph Nodes In Early-Stage Ovarian Cancer (MELISA) trial prospectively assessed the SLN detection rate and the diagnostic accuracy of the SLN mapping technique in patients with early-stage epithelial ovarian cancer. MethodsThis prospective, single-arm study included patients diagnosed with early-stage epithelial ovarian cancer (FIGO stages I and II), via either primary surgery or re-staging surgery. SLN mapping was performed by injecting 0.2 mL of 37-mBq 99mTc-nanocoloid albumin and 2 mL of 2.5 mg/mL indocyanine green into the infundibulopelvic and utero-ovarian ligaments. After removal of SLNs, a complete systematic pelvic and para-aortic lymphadenectomy was performed. SLN Ultrastaging analysis was applied. The primary outcome was the overall SLN detection rate, either with one or both tracers. Secondary outcomes were the diagnostic accuracy of detecting lymph node metastases and factors that may influence SLN detection. ResultsThirty patients were included. SLNs were identified in 27 patients (90%). Detection rates in primary and re-staging surgery were 89% and 92%, respectively. Para-aortic drainage was the predominant lymphatic spread, observed in 26 of 27 patients. Ultrastaging pathologic reports listed 1 SLN with macrometastasis, 1 with micrometastasis, and 5 with isolated tumor cells; the sensitivity of SLN mapping was 100%, with a false-negative rate of 0%. Univariate analysis showed a nonsignificant higher proportion of patients with uterine fibroids, adenomyosis, and endometriosis (100%, 67%, 67%, respectively) in patients in whom SLNs were not detected. ConclusionSLN mapping has a high detection rate (90%) and is an accurate technique for detecting lymph node involvement in early-stage epithelial ovarian cancer. SLN mapping is a potential alternative to systematic lymphadenectomy to reduce associated morbidity, but further research is needed to evaluate the impact of SLN mapping on oncologic outcomes and its cost-effectiveness.

Detection and dissection of sentinel nodes in endometrial endometrioid cancer with indocyanine green using PinPoint laparoscopy: Analysis of the learning curve

ObjectiveEarly-stage endometrial endometrioid adenocarcinoma is managed through laparoscopic total hysterectomy with bilateral salpingo-oophorectomy and pelvic lymphadenectomy. Detection of positive nodes is rare, and lymphadenectomy may involve complications. Pelvic sentinel lymph node dissection can prevent complete dissection. Herein, we evaluated the learning curve of sentinel lymph node dissection using indocyanine green.Study design: All surgeries for endometrial endometrioid adenocarcinoma were performed laparoscopically with indocyanine green to detect sentinel nodes. The primary outcome was the ability to identify and resect sentinel lymph nodes on each side. The secondary outcome was correspondence between the frozen section histology of the nodes with the final histology. ResultsAmong 31 patients with endometrial endometrioid adenocarcinoma treated between October 2018 and August 2020, 29 who underwent laparoscopy using indocyanine green were enrolled. Complete lymphadenectomy was performed in 16 patients. Failure to recognize sentinel nodes on right and left sides occurred in 10.34% and 0% of cases, respectively. The median number of recognized and dissected sentinel nodes was 1 on both sides (range 0–5). One patient had a lymph node positive for malignancy on histology (3.45%) on both sides. There were 13 and 14 cases of negative frozen sections on the right and left sides, respectively, and 1 case of a positive frozen section with positive whole pelvic lymph nodes. ConclusionSentinel node dissection using indocyanine green in endometrial endometrioid adenocarcinoma has a distinct learning curve; however, it is practical and achievable for skilled surgeons.

Sentinel-node biopsy in apparent early stage ovarian cancer: final results of a prospective multicentre study (SELLY)

AimTo evaluate the sensitivity and specificity of sentinel-lymph-node mapping compared with the gold standard of systematic lymphadenectomy in detecting lymph node metastasis in apparent early stage ovarian cancer. MethodsMulticenter, prospective, phase II trial, conducted in seven centers from March 2018 to July 2022. Patients with presumed stage I-II epithelial ovarian cancer planned for surgical staging were eligible. Patients received injection of indocyanine green in the infundibulo-pelvic and, when feasible, utero-ovarian ligaments and sentinel lymph node biopsy followed by pelvic and para-aortic lymphadenectomy was performed. Histopathological examination of all nodes was performed including ultra-staging protocol for the sentinel lymph node. Results174 patients were enrolled and 169 (97.1 %) received study interventions. 99 (58.6 %) patients had successful mapping of at least one sentinel lymph node and 15 (15.1 %) of them had positive nodes. Of these, 11 of 15 (73.3 %) had a correct identification of the disease in the sentinel lymph node; 7 of 11 (63.6 %) required ultra-staging protocol to detect nodal metastasis. Four (26.7 %) patients with node-positive disease had a negative sentinel-lymph-node (sensitivity 73.3 % and specificity 100.0 %). ConclusionsIn a multicenter setting, identifying sentinel-lymph nodes in apparent early stage epithelial ovarian cancer did not reach the expected sensitivity: 1 of 4 patients might have metastatic lymphatic disease unrecognized by sentinel-lymph-node biopsy. Nevertheless, 35.0 % of node positive patients was identified only thanks to ultra-staging protocol on sentinel-lymph-nodes.

Pelvic lymphadenectomy: Evaluating nodal stage migration and will rogers effect in bladder cancer

IntroductionPelvic lymphadenectomy (PLND) alongside radical cystectomy (RC), provides crucial diagnostic and therapeutic value in patients with bladder cancer. With the advent of neoadjuvant chemotherapy and prospective data supporting standard PLND, controversy remains regarding the optimal PLND extent and patient selection. Nearly 40% of patients may not receive adequate PLND, even though 25% of patients have positive lymph nodes (LN) at time of RC. We hypothesized that PLND still remains an important facet of bladder cancer treatment. To clarify the prognostic importance of nodal yield, we performed a retrospective investigation of a heterogenous population (pTanyNx/0M0) of patients undergoing RC. MethodsFrom the Surveillance, Epidemiology, and End Results (SEER) program, we identified pTanyNx/0M0 bladder cancer patients undergoing RC from 2004 to 2015. Kaplan Meier curves and Cox proportional hazards models assessed cancer-specific survival. Patients were analyzed with PLND performed as the primary covariate. Survival analysis then stratified patients undergoing PLND by LN yield, both as a continuous and categorial variable (≤10, 11–20, 21–30, and >30), and T stage. ResultsThe final cohort included pTanyNx/0M0 patients with urothelial bladder cancer (n = 12,096); median follow up was 39 (IQR: 17–77) months. PLND was performed in 81.45% of patients with a median LN yield of 14 (IQR: 7–23). Most commonly, patients had T2 disease (44.68%). After controlling for age and T stage, patients receiving PLND had improved CSS (HR = 0.56, [95% CI: 0.51–0.62]) compared to those that did not receive PLND. When grouping patients by LN yield, survival improved in a “dose dependent” manner (>30 LN: HR = 0.76, [95% CI: 0.66–0.87]). We noted similar results when stratifying patients into non–muscle-invasive (NMIBC) and muscle-invasive bladder cancer (MIBC). ConclusionsIn a large contemporary series of pTanyNx/0M0 bladder cancer patients, we found a significant oncologic benefit to PLND. Higher LN yield correlated to improved CSS in non–muscle-invasive and muscle-invasive disease. Our data support the possibility of occult micrometastasis even in non–muscle-invasive disease. Additionally, in light of recent advances in adjuvant immunotherapy, our results emphasize the importance of adequate nodal yield for accurate staging and optimal treatment.

Oncologic and Fertility Outcomes After Simple Trachelectomy in Women With Early Cervical Cancer

Study Objectiveto present our case series of patients with early-stage cervical cancer undergoing simple trachelectomy. Currently, radical trachelectomy is considered the most appropriate fertility preserving procedure for the treatment of early-stage cervical cancer. However, there is increasing debate on the appropriate radicality of the surgery in order to preserve oncologic safety. Designdescriptive retrospective analysis of patient records and evaluation of questionaires Settingtwo gynecologic oncologic centers, surgeries performed by one surgical team Patients36 women with early-stage cervical cancer undergoing simple trachelectomy Interventionslaparoscopic assisted simple vaginal trachelectomy MeasurementsDemographic, histological, fertility and follow-up data of all patients who underwent simple trachelectomy between 04/2007 and 7/2021 were prospectively recorded and retrospectively analyzed. Main Results36 women (mean age: 28 years) underwent simple trachelectomy of whom 81% were nulliparous. Indications for simple trachelectomy were multifocal FIGO stage IA1 (n=30), stage IA1 L1 (n=1), stage IA2 (n=2) and stage IB1 (n=3), respectively. Mandatory staging-procedure was laparoscopic pelvic lymphadenectomy, including bilateral sentinel-biopsy in 92% of the cases and systematic in 8%. Residual tumor was histologically confirmed in 8 specimens (22%). 18 women (50%) were seeking parenthood, 13 succeeded (72%). There were 16 live births, all on term, with a median fetal weight of 3110 (2330-4420) gram. One patient had a medical abortion due to fetal congenital malformation. One pregnancy is ongoing. After a median follow-up of 91.5 (9-174) months all women are alive with no evidence of disease. ConclusionSimple trachelectomy represents a de-escalation compared to radical trachelectomy and provides excellent oncologic results with an outstanding fertility rate and obstetrical outcome for patients with early cervical cancer. However, clear indications for this tailored fertility-preserving surgery have to be defined in well-designed trials.

Surgical Treatment for Early Cervical Cancer in the HPV Era: State of the Art.

Cervical cancer (CC) is the fourth most common cancer among women worldwide. The aim of this study is to focus on the state of the art of CC prevention, early diagnosis, and treatment and, within the latter, the role of surgery in the various stages of the disease with a focus on the impact of the LACC study (Laparoscopic Approach to Cervical Cancer trial) on the scientific debate and clinical practice. We have discussed the controversial application of minimally invasive surgery (MIS) for tumors < 2 cm and the possibility of fertility-sparing surgery on young women desirous of pregnancy. This analysis provides support for surgeons in the choice of better management, including patients with a desire for offspring and the need for sentinel node biopsy (SNB) rather than pelvic lymphadenectomy for tumors < 4 cm, and without suspicious lymph nodes' involvement on imaging. Vaccines and early diagnosis of pre-cancerous lesions are the most effective public health tool to tackle cervical cancer worldwide.

Preventing lower limb lymphedema after pelvic lymphadenectomy with progressive resistance exercise training: A randomized controlled trial

ObjectiveThis study aimed to assess the efficacy of a self-designed progressive resistance exercise training program for preventing the development of lower limb lymphedema. MethodsAn open-label randomized controlled trial was conducted in patients who underwent radical surgery for cervical cancer treatment in our department between October 7, 2019, and October 7, 2021. The participants were randomly assigned to one of three groups: progressive resistance exercise training, graduated compression stocking, and control group. ResultsA total of 267 patients were enrolled (89 in each group). The incidence of lower limb lymphedema was 9.0% (n = 8) in the progressive resistance exercise training group, 28.1% (n = 25) in the graduated compression stocking group, and 42.7% (n = 38) in the control group. Over the 2-year follow-up period, the risk of lower limb lymphedema was significantly lower in the progressive resistance exercise training group than in the control group, with a hazard ratio (HR) (95% confidence interval [CI]) of 0.156 (0.073–0.335). The study was underpowered to demonstrate a statistically significant reduction in risk in the graduated compression stocking group, with an HR (95% CI) of 0.624 (0.376–1.033). ConclusionsProgressive resistance exercise training is an effective strategy for preventing lower limb lymphedema after pelvic lymphadenectomy for cervical cancer. It imposes no additional economic burden and can be performed conveniently without the need for dedicated exercise facilities. This makes it particularly accessible to patients in developing countries, allowing them to exercise at their convenience. Trial registrationChiCTR1800014905.

Clear cell carcinoma arising in an ovarian remnant 19 years after oophoerctomy: case report

BackgroundOvarian remnant syndrome (ORS) is a rare complication that occurs after oophorectomy, characterized by residual ovarian tissue causing pelvic pain, masses, and various symptoms. The clinical manifestations of ORS are nonspecific, and its diagnosis relies on histological examination. Since ORS typically represents a benign ovarian lesion, there have been few reported cases of malignant transformation. In this report, we presented a unique case of ovarian clear cell carcinoma (OCCC) arising from an ovarian remnant following salpingo-oophorectomy.Case presentationOur patient was a 47-year-old female initially diagnosed with uterine myoma. She had previously undergone cesarean section and unilateral salpingo-oophorectomy. Transvaginal ultrasound and computed tomography (CT) scans revealed a soft tissue mass adjacent to the right lateral wall of the myometrium. The patient opted for transabdominal hysterectomy, left adnexal resection, laparoscopic omentectomy, appendectomy, and pelvic and abdominal lymphadenectomy. The final pathology results confirmed the diagnosis of OCCC, consistent with ORS. The patient subsequently received six cycles of intravenous chemotherapy using the carboplatin/paclitaxel (TC) regimen (paclitaxel liposomes 175 mg/m², carboplatin AUC 5). After 3 years of follow-up, the patient’s condition remained normal.ConclusionORS can significantly impact patients’ quality of life and pose challenges for clinicians. Complete excision of ovarian tissue during the initial surgery is crucial in preventing ORS recurrence and potential malignant transformation of ovarian remnants.

Surgical Outcomes in Early-Stage Cervical Cancer Following Radical Hysterectomy in a Resource-Limited Setting: The Experience of the National Cancer Institute (Apeksha Hospital, Maharagama), Sri Lanka.

Introduction Cervical carcinoma is the commonest gynecological malignancy in Sri Lanka, and this incidence is rising. Radical hysterectomy is the preferred treatment for stages IB1, IB2, and selected cases of stages IIA1. Although surgery is feasible unless the parametrium is involved, careful patient selection is crucial in order to prevent the patient from receiving a dual mode of radical treatment (surgery and radiotherapy). Pre-operative imaging with MRI and PET-CT can accurately determine the tumor size and the lymph node metastasis. In a resource-limited setting, management is challenging as access to MRI and PET-CT is limited. This study was carried out to evaluate the surgical outcomes, five-year survival, and disease-free survival following radical hysterectomies at the National Cancer Institute, Sri Lanka, which performs the largest number of radical hysterectomies annually in the country. Methods Seventy-four patients who underwent radical hysterectomy, along with pelvic lymphadenectomy, between July 2015 to January 2017 at the National Cancer Institute, Sri Lanka (Apeksha Hospital Maharagama), were reviewed retrospectively, analyzing their clinical data and histopathological findings. Univariate analysis was performed to identify associated factors and mean survival. The Kaplan-Meier method was used for survival analysis. Results With a median follow-up of 63.5 months, five-year disease-free survival was 94.5%, and the five-year overall survival was 95.9%. There is a statistically significant association between mean survival and the cell type, presence of LVSI, and residual tumor on the hysterectomy specimen. Only four patients developed recurrences and four patients died during the follow-up. Eighteen (24.3%) patients needed blood transfusion postoperatively and no cases of bladder or bowel dysfunction in the one year post-operatively.Thirty patients (40.5%) required postoperative adjuvant treatment. Conclusions This analysis shows excellent surgical and oncological outcomes following radical hysterectomy as a primary treatment and comparable five-year disease-free survival with available global figures, despite the multiple scarcity of resources. Further studies are needed to assess the national-level status, and limited access to imaging during surgical planning poses a risk for patients receiving dual modes of radical treatment.

IMPACT OF ADJUVANT CHEMOTHERAPY AFTER RADICAL CYSTECTOMY FOR PATIENTS WITH LOCALLY ADVANCED BLADDER CANCER

(Objective) The study aimed to retrospectively evaluate the therapeutic effects of adjuvant chemotherapy (AC) in patients following radical cystectomy (RC) in locally advanced bladder cancer. (Methods) A single-center-derived database registered 227 patients diagnosed with muscle-invasive bladder cancer and treated with RC and pelvic lymphadenectomy between March 2003 and December 2021. Of these, patients diagnosed with non-organ-confined diseases were classified as either pT3-T4 or pN-positive without distant metastasis. Platinum-based AC was administered for the following categories: two courses for patients with pT3-T4 and pN-negative and three courses for those with pTany and pN-positive. The primary endpoint was the disease-free survival (DFS) and overall survival (OS) between the patients receiving and not receiving AC. (Results) Among all patients, 90 were diagnosed with non-organ-confined disease: 43 (47.8%) were treated with AC and the remaining 47 (52.2%) were left untreated. The methotrexate, vinblastine, doxorubicin, and cisplatin regimen; the gemcitabine and cisplatin regimen; and the gemcitabine and carboplatin regimen were administered to 14 (32.6%), 25 (58.1%), and 4 (9.3%) patients, respectively. With a median follow-up period of 26 months, the groups that received and did not receive AC had 2-year DFS rates of 36.3% and 25.9% (median DFS time: 15 vs. 8 months, p=0.026) and 2-year OS rates of 64.3% and 41.4% (median OS time: 38 vs. 18 months, p=0.064), respectively. In patients with pT3-T4 and pN-negative, no significant difference in the median DFS and OS between the AC and non-AC groups was observed. However, in patients with pTany and pN-positive, the DFS (median: 14 vs. 4.5 months, p=0.002) and OS (38 vs. 11.5 months, p=0.009) were longer in the AC than those in the non-AC group, respectively. The multivariate Cox regression analysis revealed that AC administration was an independent predictor for DFS (hazard ratio: 0.44, 95% confidence interval: 0.24-0.79, p=0.006). (Conclusion) Platinum-based AC following RC significantly improved DFS in pN-positive patients with locally advanced bladder cancer.

Does neo-adjuvant chemotherapy improve the negative effect of lymphovascular invasion in survival after radical cystectomy?

PurposeThere is a lack of studies in the literature to evaluate the impact of the specific benefit of the use of neo-adjuvant chemotherapy (NAC) on the negative effect of lymphovascular invasion (LVI) on prognosis. We aimed to evaluate the survival differences of patients according to the presence of LVI with and without administration of NAC before radical cystectomy (RC). Materials and methodsWe retrospectively evaluated data of the patients who underwent RC with pelvic lymphadenectomy and urinary diversion for bladder cancer recorded in the bladder cancer database of the Turkish Uro-oncology Association between 2007 and 2021. Patient demographics, follow-up time and overall survival (OS) were noted. ResultsA total of 633 subjects included in the analyses. Median follow-up time was 24 months (IQR 12–54). Five years OS of the whole cohort was 55.1%. This was 54.7% and 59.9% in NAC- and NAC+ groups (P = 0.683), respectively. It was also 35.7% and 65.7% in LVI+ and LVI- patients (P < 0.0001), respectively. There was a significant difference between LVI+ and LVI- patients (33.2% vs. 68.2%, P < 0.0001) in NAC- group, but similar 5-year OS was found (53.2% vs. 64.5%, P = 0.552) in NAC+ group. In multivariable analyses, female gender, pN stages, presence of variant histology and LVI were significant independent predictive factors for OS in the whole cohort and in the NAC- group. However, gender association, pN stages and LVI lost significance in NAC+ group. ConclusionPresence of LVI significantly reduced OS, and the NAC treatment improved the negative effects of LVI on OS. Our findings encourage the use of NAC before RC.

The fluorescence imaging for laparoscopic and laparotomic endometrial sentinel lymph node biopsy (FILLES) trial: Siriraj gynecologic sentinel node of endometrial cancer (SiGN-En) study.

The objective of this study is to establish the detection rate of sentinel lymph node (SLN) biopsies and to determine the sensitivity and false-negative rate of SLN biopsies compared with those of systematic pelvic and para-aortic lymphadenectomies in endometrial cancer. This prospective cohort study enrolled patients with endometrial cancer who were scheduled for surgical staging. Patients with a history of chemotherapy or radiotherapy, an abnormal liver function test, or an allergy to indocyanine green (ICG) were excluded. All patients underwent surgical staging with an ICG injection at the cervix. SLNs were identified by a near-infrared fluorescent camera. All SLNs were sent to a pathologist for ultrastaging. From November 2019 to June 2023, 142 patients underwent SLN mapping and surgical staging. SLNs were not detected bilaterally in 8 patients. The detection rate of the SLN biopsies in this study was 91.2%. Thus, the accuracy of the SLN biopsies was 97.6%. The sensitivity for finding metastatic SLNs was 84.2%, with a negative predictive value of 97.22%. A SLN biopsy in endometrial cancer has a high detection rate and high accuracy. However, surgical expertise and a learning curve are required.

Outcome of radical cystectomy in remote area of Pakistan: Recep Tayyip Erdogan Hospital, Muzaffargarh (IHHN)

Background: Radical cystectomy with bilateral pelvic lymphadenectomy is the standard treatment for high grade/ muscle invasive urinary bladder tumor. Continent or incontinent urinary diversion is the part of this major operation. High volume centers perform routinely but low volume centers do less frequent. It might be because of availability of equipment and trained surgeon in remote area of Pakistan. Objectives: to assess the results of radical cystectomy at a low-volume center for high-grade muscle-invasive bladder tumours. For patients aged 50 to 75, this involves evaluating surgical complications, overall survival, and the absence of tumour recurrence throughout a one-year follow-up period. Study design: A Retrospective StudyDuration and place of study: Recep Tayyip Erdogan hospital, Muzaffargarh from October 2018 to August 2022 Methods: total Cases from both genders and 50 to 75 years old with High grade/ Muscle invasive urinary bladder carcinoma, incomplete resection during TURBT due to high volume of mass (irresistible) included. Performa designed for collection of information. All the patients underwent same procedure by same urologist. Patients were followed for one year after surgery. Results: All participants were followed for one year. 33.3% patients had paralytic ileus (CDC I), 13.3% had wound infection (CDC I) and 6.7% had urinary leakage (CDC IIIb). There was 86.6% overall survival rate. 6.7% lost to follow up. Mean operative time was 308 ±95 minutes. There was no recurrence noted throughout the study period. Conclusion: Good operative results can also achieve at low volume centers. High level of surveillance and expertise help to achieve better outcomes in remote.

Predictors of Non-Sentinel Lymph Node Metastasis in Patients with Positive Sentinel Lymph Node in Early-Stage Cervical Cancer: A SENTICOL GROUP Study.

The goal of this study was to identify the risk factors for metastasis in the remaining non-sentinel lymph nodes (SLN) in the case of positive SLN in early-stage cervical cancer. An ancillary analysis of two prospective multicentric databases on SLN biopsy for cervical cancer (SENTICOL I and II) was performed. Patients with early-stage cervical cancer (FIGO 2018 IA to IIA1), with bilateral SLN detection and at least one positive SLN after ultrastaging, were included. 405 patients were included in SENTICOL I and Il. Fifty-two patients had bilateral SLN detection and were found to have SLN metastasis. After pelvic lymphadenectomy, metastatic involvement of non-SLN was diagnosed in 7 patients (13.5%). Patients with metastatic non-SLN were older (51.9 vs. 40.8 years, p = 0.01), had more often lympho-vascular space invasion (LVSI) (85.7% vs. 35.6%, p = 0.03), and had more often parametrial involvement (42.9% vs. 6.7%, p = 0.003). Multivariate analysis retained age (OR = 1.16, 95% IC = [1.01-1.32], p = 0.03) and LVSI (OR = 25.97, 95% IC = [1.16-582.1], p = 0.04) as independently associated with non-SLN involvement. Age and LVSI seemed to be predictive of non-SLN metastasis in patients with SLN metastasis in early-stage cervical cancer. Larger cohorts are needed to confirm the results and clinical usefulness of such findings.

Evaluating the Oncological and Functional Outcomes in 167 Patients Undergoing Laparoscopic Radical Prostatectomy: Could Laparoscopy Still be a Viable Option in Suitable Patients?

Aim: To evaluate the oncological and functional outcomes of 167 patients who underwent laparoscopic radical prostatectomy (LRP). Materials and Methods: The retrospective study included 167 patients who were treated with LRP due to clinically localized prostate cancer between January 2007 and April 2012. Most of the patients were treated with the extraperitoneal approach. Preoperative evaluations included age, serum prostate-specific antigen (PSA) level, and biopsy Gleason score. Perioperative evaluations included duration of operative time and anastomosis time, blood loss (milliliter), and complications. Postoperative evaluations included length of hospital stay and catheterization time. Continence and erectile function were evaluated both pre- and postoperatively. The patients who used no pads or no more than one pad daily and the ones who had only a few urine leakages on effort or exertion were accepted as continent. Postoperative potency was defined as the ability to achieve sexual intercourse with or without the use of PDE-5 inhibitors. Results: Mean age and mean operative time were 62.4 ± 6.0 years and 220.5 ± 45.6 minutes, respectively. Mean anastomosis time was 35.6 ± 9.8 minutes. Mean serum PSA level and mean Gleason score were 17.5 ± 9.97 ng/mL and 6.16 ± 0.42, respectively. Pelvic lymphadenectomy was performed in 94 patients and nerve-sparing procedures in 61 patients. The pathological analysis revealed positive surgical margin in 35 patients (20.9%). Bilateral and unilateral nerve-sparing LRP procedures were performed in 51 (30.5%) and 10 (6%) patients, respectively. At 12 months after surgery, 3 (1.8%) patients were using 2 or more pads per day, 19 (26.4%) patients were satisfied with erection, hardness, and duration of intercourse, and 9 (12.5%) patients had an erection with insufficient hardness and duration. Conclusion: LRP is an acceptable method in localized prostate cancer due to its perioperative and early postoperative results.

Splenic sarcoid reaction mimicking metastases in patients after uterine cancer surgery: a report of two cases

BackgroundTumor-associated sarcoid reactions have been observed with various tumors; however, they have not been reported with uterine cancer. We present two cases of splenic sarcoid reactions that mimicked metastases a few years after uterine cancer surgery.Case presentationCase 1 involved a 67-year-old female patient diagnosed with endometrial cancer (pT1aN0M0, pStage Ia, grade 1). The patient underwent open total abdominal hysterectomy and bilateral salpingo-oophorectomy with pelvic lymphadenectomy. Three years after the initial surgery, computed tomography (CT) and positron emission tomography CT showed multiple splenic masses with increasing numbers and sizes. Splenic metastases were diagnosed, and laparoscopic splenectomy was performed. The histopathological analysis revealed sarcoid reactions in the spleen. Case 2 involved a 47-year-old female patient diagnosed with endometrial cancer (pT1aN0M0, pStage Ia, grade 1). The patient underwent laparoscopic total abdominal hysterectomy and bilateral salpingo-oophorectomy with pelvic lymphadenectomy. Two years after the initial surgery, multiple splenic masses were observed. We performed laparoscopic splenectomy for the splenic metastases. Granuloma formations were identified in the splenic specimen and perisplenic lymph nodes that were removed simultaneously, resulting in a final diagnosis of sarcoid reaction. A review of the lymph nodes at the time of the previous uterine surgery revealed granuloma formation. Other than the presence of splenic masses, no findings suggestive of recurrence were observed in these cases. Uterine cancer and sarcoid reactions progressed without recurrence after splenectomy.ConclusionsTo the best of our knowledge, this is the first report of the late development of splenic sarcoid reactions after uterine cancer surgery. Sarcoid reactions and metastases are difficult to diagnose based on preoperative imaging results. However, reviewing the specimen at the time of the initial resection, the number of lesions, and the clinical findings (other than imaging findings) may aid in the determination of the correct diagnosis.

Preperitoneal vas deferens infiltration in high-risk prostate cancer.

The objective of this study is to evaluate the prevalence and the importance of preperitoneal vas deferens (VD) infiltration in high-risk prostate cancer (PCa). In this prospectively designed study, we included 332 high-risk PCa patients with a Briganti score >5%, who were treated by robot-assisted radical prostatectomy between July 2017 and February 2022 at the Urology Department, SLK Kliniken Heilbronn. In addition to the standard histological analysis of the distal VD, which was attached to the prostate specimen, we analysed the infiltration status of preperitoneal VD in this cohort. The preperitoneal VD, which represents the middle part of ductus deferens and extends between the internal inguinal ring and obturator fossa, was resected during extended pelvic lymphadenectomy. Distal and preperitoneal VD status was registered together with preoperative and postoperative disease characteristics. Descriptive analysis methods and logistic regression analysis were used. Briganti score of the target cohort had a median value of 19%, while 235 patients (70.8%) of the group demonstrated a locally advanced disease. The Grade Group at prostatectomy specimen was at least 3 for 286 patients (86.1%). Distal VD infiltration was found in 20 patients (6%) and preperitoneal VD infiltration in two patients (0.6%). Distal VD infiltration was not associated with an increased possibility for positive surgical margins or nodal status among pT3b patients, while both patients with preperitoneal VD infiltration were characterized by highly aggressive disease in locally advanced stage and bilateral distal VD infiltration. PCa extension along VD may reach a more proximal point of VD than the reported from the existing data infiltration of VD adjacent to seminal vesicles. This rare manifestation of PCa local extension may be the intermediate step to the rare cases of recurrence in the testicles. However, more robust data are needed to confirm the aforementioned hypothesis. Distal VD infiltration seems to have no additional prognostic value among patients with infiltrated seminal vesicles.

“Cheerios in the lung” as first metastases from endometrial endometrioid adenocarcinoma with adequate response to immunotherapy

BackgroundMetastases from endometrial carcinoma to the lungs are uncommon and cavitating metastases are even rarer. In some cases, lung cavitating metastases may resemble diffuse “Cheerios in the lung.”Case presentationA 58-year-old woman, smoker, with a history of hysteroannessiectomy and pelvic lymphadenectomy for a low stage endometrial endometrioid adenocarcinoma, came under our attention for dry cough without fever that persisted for over three months, and computed tomography (CT) revealed diffuse cavitating lung metastases resembling "Cheerios in the lung".After standard chemotherapy proved ineffective, Lenvatinib plus Pembrolizumab (immunotherapy) was administrated, leading to the disappearance of all lung nodules, leaving behind a diffuse emphysematous-like pattern.ConclusionsThis case is a rare example of metastatic endometrioid adenocarcinoma, manifested with chronic dry cough, with “Cheerios in the lung” appearence. The metastases responded well to immunotherapy, resulting in the regression of nodules into areas of diffuse emphysematous-like changes.
