OBJECTIVE
To evaluate the effectiveness of methylene blue dye in detecting sentinel lymph nodes (SLNs) in women with early-stage operable (defined as FIGO I-IIA) cervical cancer. It also aims to evaluate procedural challenges and accuracy.
METHOD
This prospective study, which focused on 20 women with early-stage cervical cancer, was carried out between June 2016 and December 2017. These patients had SLN mapping with methylene blue dye injections and thorough examinations, including imaging. All patients underwent radical hysterectomy and complete bilateral pelvic lymphadenectomy. No additional investigation was done on the lymph node in cases where a metastasis was found in the first H&E-stained segment of the sentinel node.
RESULT
20 patients were included in the analysis. The median age of the subjects was 53, and 95 % of them had squamous cell carcinoma. 90 % of the time, the identification of SLNs was effective, and 55 SLNs were found, of which 52.7 % were on the right side of the pelvis and 47.3 % on the left. The obturator group had the most nodes, followed by the external and internal iliac groups in descending order of occurrence. Metastasis was detected in 3 patients, resulting in a sensitivity of 100 % and a specificity of 93.75 % for SLN biopsy. Notably, no false-negative SLNs were found. Complications related to methylene blue usage included urine discoloration in 30 % of patients.
CONCLUSION
This trial highlights the promising efficacy and safety of methylene blue dye alone for SLN identification in early-stage operable cervical cancer, with a notably higher success rate. Despite limitations like a small sample size, healthcare professionals and researchers can build upon the insights from this study to enhance cervical cancer management.

Comparative Study
PURPOSE
We conducted this study to evaluate the efficacy of total hysterectomy versus radical hysterectomy in the treatment of neuroendocrine cervical cancer (NECC).
METHODS
Eligible NECC patients were identified from the Surveillance, Epidemiology and End Results (SEER) database. Demographic characteristics, clinical treatment and survival of the patients were collected. The overall survival (OS) and cancer-specific survival (CSS) were estimated by Kaplan-Meier analysis with log-rank test.
RESULTS
A total of 286 patients were included, with 104 patients undergoing total hysterectomy and 182 patients undergoing radical hysterectomy. The 5-year OS were 50.8% in the total hysterectomy group and 47.5% in the radical hysterectomy group (p = 0.450); and the corresponding 5-year CSS were 51.6% and 49.1% (p = 0.494), respectively. Along with surgery, radiotherapy was given to 49.0% of patients in the total hysterectomy group and 50.5% in the radical hysterectomy group; and chemotherapy was administered to 77.9% of patients in the total hysterectomy group and 85.7% in the radical hysterectomy group. Unexpectedly, in patients who received adjuvant radiotherapy with or without chemotherapy, the OS was superior in the total hysterectomy group compared with the radical hysterectomy group (p = 0.034). While in patients who received chemotherapy alone and those who received neither radiotherapy nor chemotherapy, the OS still remained comparable between the total hysterectomy and radical hysterectomy group.
CONCLUSION
Compared with radical hysterectomy, total hysterectomy was not associated with compromised survival prognosis in patients with NECC. Total hysterectomy has the potential to be a surgical alternative in the multimodal management of NECC.

Comparative Study
Comparison of outcomes between early-stage cervical cancer patients without high-risk factors undergoing adjuvant concurrent chemoradiotherapy and radiotherapy alone after radical surgery.
PURPOSE
For patients with early-stage cervical cancer without high-risk factors, there is no consensus regarding the optimal postoperative treatment regimen and whether postoperative concurrent radiochemotherapy (CCRT) is superior to radiotherapy (RT) alone.
PATIENTS AND METHODS
The medical records of patients with stage I-IIA cervical cancer, who underwent radical surgery and postoperative RT or CCRT between June 2012 and December 2017, were retrospectively reviewed. Patients with any high-risk factors, including positive pelvic lymph node(s), positive resection margin(s), and parametrial invasion, were excluded. Patients with large tumors (≥ 4 cm), deep stromal invasion (≥ 1/2), and lymphovascular space involvement were categorized as the intermediate-risk group. Patients without intermediate-risk factors were categorized as the low-risk group.
RESULTS
A total of 403 patients were enrolled and divided into 2 groups according to postoperative treatment: RT alone (n = 105); and CCRT (n = 298). For risk stratification, patients were also divided into 2 groups: intermediate-risk (n = 350); and low-risk (n = 53). The median follow-up was 51.7 months. Patients in the intermediate-risk group and those with multiple intermediate-risk factors were more likely to undergo CCRT. For patients who underwent RT alone or CCRT in the intermediate-risk group, 5-year overall survival (OS) rates were 93.4% and 93.8% (p = 0.741), and 5-year disease-free survival (DFS) rates were 90.6% and 91.4%, respectively (p = 0.733). Similarly, for patients who underwent RT alone or CCRT in the low-risk group, the 5-year OS rates were 100.0% and 93.5% (p = 0.241), and 5-year DFS rates were 94.4% and 93.5%, respectively (p = 0.736). Adjuvant CCRT or RT were not independent risk factors for either OS or DFS. Patients who underwent CCRT appeared to develop a higher proportion of grade ≥ 3 acute hematological toxicities than those in the RT group (44.0% versus 11.4%, respectively; p < 0.001). There was no significant difference in grade ≥ 3 chronic toxicities of the urogenital and gastrointestinal systems between the CCRT and RT groups.
CONCLUSION
There was no significant difference in 5-year OS and DFS rates between patients with early-stage cervical cancer without high-risk factors undergoing postoperative CCRT versus RT alone. Patients who underwent CCRT appeared to develop a higher proportion of grade ≥ 3 acute hematological toxicities than those who underwent RT alone.

BACKGROUND/AIM
Endometrial cancer (EC) is the predominant malignancy among gynecologic cancers and ranks fourth among all types of cancer. Recently, researchers have focused on the development of new prognostic biomarkers. Subunits of the SWI/SNF protein complex, like the ARID1 and BRG1, have been associated with the development of endometrial cancer. The present study aimed to evaluate the expression patterns of ARID1A and BRG1 in a collection of endometrioid adenocarcinomas of the uterus using immunohistochemistry.
PATIENTS AND METHODS
The study comprised a total of thirty-three individuals diagnosed with stage I endometrioid endometrial cancer, treated with radical hysterectomy. The histological material was then examined to assess the cytoplasmic and nuclear expression of the proteins.
RESULTS
ARID1A exhibited expression in both the cytoplasm and nucleus of cancer cells, whereas BRG1 was mainly expressed in the nuclei. In addition, ARID1A exhibited a notable decrease in expression in grade 3 histology, with no significant correlation with the depth of myometrial invasion. The reduced expression was highly related to tumor expansion into the endocervix. The findings demonstrated a total absence of ARID1A expression in 27% of endometrioid carcinomas, with a significant reduction in expression in an additional 51% of cancer cells. These findings align with the most recent published data. In contrast, in the current study, BRG1 was rarely down-regulated and was extensively expressed in the majority of endometrioid carcinomas, preventing the possibility of statistical analysis.
CONCLUSION
In summary, ARID1A expression loss can be used as a biomarker to guide post-operative therapy; however, further investigation is needed, especially for early-stage endometrial cancer.

Comparative Study
OBJECTIVE
The aim of this study was to compare the incidence of intra-operative and post-operative complications in open and minimally invasive radical hysterectomy for patients with early-stage cervical cancer.
METHODS
Data were collected from the SUCCOR database of 1272 patients with stage IB1 cervical cancer (International Federation of Gynecology and Obstetrics (FIGO), 2009) who underwent radical hysterectomy in Europe between January 2013 and December 2014. We reviewed the duration of the surgeries, estimated blood loss, length of hospital stay, intra-operative and post-operative complications. The inclusion criteria were age ≥18 years and histologic type (squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma). Pelvic MRI confirming a tumor diameter ≤4 cm with no parametrial invasion and a pre-operative CT scan, MRI, or positron emission tomography CT demonstrating no extra-cervical metastatic disease were mandatory. Outcomes of interest were any grade >3 adverse events, intra-operative adverse events, post-operative adverse events, length of hospital stay, length of operation, and blood loss.
RESULTS
The study included 1156 patients, 633 (54%) in the open surgery group and 523 (46%) in the minimally invasive surgery group. Median age was 46 years (range 18-82), median body mass index 25 kg/m (range 15-68), and 1022 (88.3%) patients were considered to have an optimal performance status (ECOG Performance Status 0). The most common histologic tumor type was squamous carcinoma (n=794, 68.7%) and the most frequent FIGO staging was IB1 (n=510, 44.1%). In the minimally invasive surgery group the median duration of surgery was longer (240 vs 187 min, p<0.01), median estimated blood loss was lower (100 vs 300 mL, p<0.01), and median length of hospital stay was shorter (4 vs 7 days, p<0.01) compared with the abdominal surgery group. There was no difference in the overall incidence of intra-operative and post-operative complications between the two groups. Regarding grade I complications, the incidence of vaginal bleeding (2.9% vs 0.6%, p<0.01) and vaginal cuff dehiscence was higher in the minimally invasive surgery group than in the open group (3.3% vs 0.5%, p<0.01). Regarding grade III post-operative complications, bladder dysfunction (1.3% vs 0.2%, p=0.046) and abdominal wall infection (1.1% vs 0%, p=0.018) were more common in the open surgery group than in the minimally invasive surgery group. Ureteral fistula was more frequent in the minimally invasive group than in the open surgery group (1.7% vs 0.5%, p=0.037).
CONCLUSION
Our study showed that there was no significant difference in the overall incidence of intra-operative and post-operative complications between minimally invasive radical hysterectomy and the open approach.

BACKGROUND
Cervical stump malignancies are an uncommon finding post subtotal hysterectomy. Tumors arise from a primary cervical origin with an incidence of 1-5%. Other described malignancies can include uterine origin, ovarian origin or as metastases from another primary site. A uterine primary is an extremely rare entity and can result from remnant endometrial tissue at the stump apex.
CASE
70yo female with a history of remote supracervical hysterectomy for benign indication who presented with postmenopausal spotting. Endocervical curettage of the endocervical stump revealed a grade 2 endometrioid endometrial adenocarcinoma. She was taken to the operating for a robotic radical stump trachelectomy and sentinel lymph node dissection.
CONCLUSIONS
The surgical video delineates key surgical steps of robotic radical stump trachelectomy including robotic port placement and injection of ICG dye, adhesiolysis and restoration of normal anatomy, opening of the pelvic spaces and exposure of the retroperitoneum, identification and excision of pelvic sentinel lymph nodes, bladder dissection, ureterolysis and ligation of uterine remnant, ureteric tunnel dissection and mobilization of parametrial wing, delineation of a vaginal margin, colpotomy and specimen removal, and vaginal cuff closure.

OBJECTIVE
Radical vaginal trachelectomy is a fertility-preserving treatment for patients with early cervical cancer. Despite encouraging oncologic and fertility outcomes, large studies on radical vaginal trachelectomy are lacking.
METHOD
Demographic, histological, fertility, and follow-up data of consecutive patients who underwent radical vaginal trachelectomy between March 1995 and August 2021 were prospectively recorded and retrospectively analyzed.
RESULTS
A total of 471 patients of median age 33 years (range 21-44) were included. 83% (n=390) were nulliparous women. Indications were International Federation of Gynecology and Oncology (FIGO, 2009) stages IA1 with lymphvascular space involvement (LVSI) in 43 (9%) patients, IA1 multifocal in 8 (2%), IA2 in 92 (20%), IB1 in 321 (68%), and IB2/IIA in 7 (1%) patients, respectively. LVSI was detected in 31% (n=146). Lymph node staging was performed in 151 patients (32%) by the sentinel node technique with a median of 7 (range 2-14) lymph nodes and in 320 (68%) by systematic lymphadenectomy with a median of 19 (range 10-59) lymph nodes harvested. Residual tumor was histologically confirmed in 29% (n=136). In total, 270 patients (62%) were seeking pregnancy of which 196 (73%) succeeded. There were 205 live births with a median fetal weight of 2345 g (range 680-4010 g). Pre-term delivery occurred in 94 pregnancies (46%). After a median follow-up of 159 months (range 2-312), recurrences were detected in 16 patients (3.4%) of which 43% occurred later than 5 years after radical vaginal trachelectomy. Ten patients (2.1%) died of disease (five more than 5 years after radical vaginal trachelectomy). Overall survival, disease-free survival, and cancer-specific survival were 97.5%, 96.2%, and 97.9%, respectively.
CONCLUSION
Our study confirms oncologic safety of radical vaginal trachelectomy associated with a high chance for childbearing. High rate of pre-term delivery may be due to cervical volume loss. Our long-term oncologic data can serve as a benchmark for future modifications of fertility-sparing surgery.

BACKGROUND
Malignant triton tumors (MTTs) comprise a subgroup of malignant peripheral nerve sheath tumors (MPNSTs) that exhibits rhabdomyosarcomatous differentiation and follow an aggressive course. MTTs are primarily located along peripheral nerves. Cases of MTTs in the abdominal wall have not been reported. MTT has a poorer prognosis than classic MPNSTs, and accurate diagnosis necessitates a keen understanding of the clinical history and knowledge of its differential diagnosis intricacies. Treatment for MTTs mirrors that for MPNSTs and is predominantly surgical.
CASE SUMMARY
A 49-year-old woman presented with a subcutaneous mass in her lower abdominal wall and a pre-existing surgical scar that had grown slowly over 3-4 months before the consultation. She had previously undergone radical hysterectomy and concurrent chemo-radiotherapy for cervical cancer approximately 5 years prior to the consultation. Abdominal computed tomography (CT) showed a 1.3 cm midline mass in the lower abdomen with infiltration into the rectus abdominis muscle. There was no sign of metastasis (T1N0M0). An incisional biopsy identified sporadic MTT of the lower abdomen. A comprehensive surgical excision with a 3 cm margin inclusive of the peritoneum was executed. Subsequently, the general surgeon utilized an approach akin to the open peritoneal onlay mesh technique. The patient underwent additional treatment with an excision shaped as a mini-abdominoplasty for the skin defect. No complications arose, and annual follow-up CTs did not show signs of recurrence or metastasis.
CONCLUSION
An abdominal MTT was efficaciously treated with extensive excision and abdominal wall reconstruction, eliminating the need for postoperative radiotherapy.

Colorectal carcinoma (CRC) represents the third most common cancer and the second highest cause of cancer-related death in the United States. CRC is particularly prevalent in patients with underlying inflammatory bowel disease. Adenocarcinoma represents more than 90% of new CRC diagnoses. The mucinous subtype of colorectal adenocarcinoma is found in approximately 10-20% of all colorectal cancer patients and is most frequently located in the proximal colon. We report a case of mucinous adenocarcinoma arising from the rectal stump of a patient who had previously undergone subtotal-colectomy with end ileostomy for Crohn's disease. She initially presented with gradually worsening chronic abdominal pain and gelatinous rectal discharge. She was found to have a complex cystic lesion communicating with her Hartman's pouch. She ultimately underwent a completion proctectomy, radical hysterectomy, and bilateral salpingo-oophorectomy in conjunction with gynecology oncology. To the best of our knowledge, this case represents the first description of a perirectal mucinous adenocarcinoma arising in a patient after subtotal-colectomy for Crohn's disease.
