RESUMO

BACKGROUND: Surgical staging is associated with a significant rate of upstaging compared to clinical/radiological staging in patients with locally advanced cervical cancer. OBJECTIVE: To analyze the stage-specific percentage of pelvic and para-aortic lymph node metastases and the upstaging ratio in a prospective randomized trial (Uterus-11). METHODS: FIGO stage IIB-IVA cervical cancer patients were randomized to surgical staging (arm A) or to clinical staging and primary chemoradiation (arm B). Arm B patients underwent CT-guided biopsy of suspicious para-aortic lymph nodes. Confirmed para-aortic metastasis patients received extended-field radiation therapy. RESULTS: A total of 234 patients were enrolled, including 120 (arm A) and 114 (arm B) treated per protocol. The groups were well balanced. Pelvic and para-aortic lymph node metastases were identified after surgical staging in 51 and 24% of patients, respectively (p < 0.001). Pelvic and para-aortic lymph node metastases were confirmed in 45 and 20% of IIB patients and in 71 and 37% of IIIB patients, respectively. Upstaging occurred in 39/120 (33%) in arm A and in 9/114 (8%) in arm B (p < 0.001). CONCLUSION: The histological results in both groups led to a considerable rate of upstaging. Oncological data from the Uterus-11 study may reveal whether modified therapy translates into a survival benefit.

RESUMO

OBJECTIVES:: To evaluate the postoperative pathological characteristics of hysterectomy specimens, preoperative cancer antigen (CA)-125 levels and imaging modalities in patients with endometrial cancer and to build a risk matrix model to identify and recruit patients for retroperitoneal lymphadenectomy. METHODS:: A total of 405 patients undergoing surgical treatment for endometrial cancer were retrospectively reviewed and analyzed. Clinical (age and body mass index), laboratory (CA-125), radiological (lymph node evaluation), and pathological (tumour size, grade, lymphovascular space invasion, lymph node metastasis, and myometrial invasion) parameters were used to test the ability to predict lymph node metastasis. Four parameters were selected by logistic regression to create a risk matrix for nodal metastasis. RESULTS:: Of the 405 patients, 236 (58.3%) underwent complete pelvic and para-aortic lymphadenectomy, 96 (23.7%) underwent nodal sampling, and 73 (18%) had no surgical lymph node assessment. The parameters predicting nodal involvement obtained through logistic regression were myometrial infiltration >50%, lymphovascular space involvement, pelvic lymph node involvement by imaging, and a CA-125 value >21.5 U/mL. According to our risk matrix, the absence of these four parameters implied a risk of lymph node metastasis of 2.7%, whereas in the presence of all four parameters the risk was 82.3%. CONCLUSION:: Patients without deep myometrial invasion and lymphovascular space involvement on the final pathological examination and with normal CA-125 values and lymph node radiological examinations have a relatively low risk of lymph node involvement. This risk assessment matrix may be able to refer patients with high-risk parameters necessitating lymphadenectomy and to decide the risks and benefits of lymphadenectomy.

RESUMO

OBJECTIVE: The aim of this study was to determine the lymph node status in a large cohort of women with endometrial cancer from the public health system who were referred to an oncology reference center in Brazil to identify candidates for the omission of lymphadenectomy based on clinicopathological parameters. METHODS: We retrospectively analyzed a cohort of 310 women with endometrial cancer (255 endometrioid, 40 serous, and 15 clear cell tumors) treated between 2009 and 2014. We evaluated the histological type, grade (low vs. high), tumor size (cm), depth of myometrial invasion (≤50%, >50%) and lymphovascular space invasion to determine which factors were correlated with the presence of lymph node metastasis. RESULTS: The factors related to lymph node involvement were tumor size (p=0.03), myometrial invasion (p<0.01), tumor grade (p<0.01), and lymphovascular space invasion (p<0.01). The histological type was not associated with the nodal status (p=0.52). Only twelve of 176 patients (6.8%) had low-grade endometrioid carcinoma, tumor size ≤2 cm and <50% myometrial infiltration. CONCLUSIONS: The omission of lymphadenectomy based on the histological type, grade, tumor size and depth of myometrial invasion is not likely to have a large impact on the surgical treatment of endometrial cancer in our population because most patients present with large and advanced tumors. New strategies are proposed that prioritize hysterectomy performed in a general hospital as soon as possible after diagnosis, followed by an evaluation of the need for lymph node dissection at a reference center.

RESUMO

BACKGROUND: Presently, the use of laparoscopy in advanced ovarian cancer (AOC) is extremely controversial. In the era of neoadjuvant chemotherapy (NACT), endoscopic debulking surgery could be a reasonable alternative for selected patients with primarily unresectable disease. OBJECTIVES: To evaluate the feasibility as well as the operative and oncologic safety of laparoscopic debulking surgery in patients with AOC submitted to NACT. METHODS: This is a pilot observational study on initially unresectable, high-grade serous ovarian cancer treated with a sequence of 6 cycles of carboplatin and paclitaxel followed by debulking surgery performed by laparoscopy (group 1) or laparotomy (group 2). The inclusion criteria were clinical complete response, CA-125 normalization, imaging without disease in critical areas, and optimal cytoreduction. RESULTS: From January 2011 to March 2014, 21 patients were included. Ten women underwent laparoscopy and 11 laparotomy. No epidemiological or oncologic differences were observed between the groups. No surgery-related casualties, intraoperative complications, conversion to laparotomy, or excessive blood loss or transfusion was detected in the laparoscopic procedures. The mean time of operation was 292 min. The length of hospital stay averaged 3.6 days. Two women in group 1 developed relevant complications. After a mean follow-up of 20 months, the recurrence rates were similar, i.e. 80% in group 1 versus 88% in group 2. Although statistical significance was not reached, the mortality related to cancer was considerably higher (20 vs. 0%; p = 0.086) and the mean chemotherapy-free interval was markedly shorter in group 1 (13.3 vs. 20.5 months; p = 0.288). CONCLUSION: Laparoscopic optimal debulking surgery after NACT is feasible and effective in selected patients. Nevertheless, laparoscopy was substantially associated with inferior oncologic results. Endoscopic cytoreduction in AOC should be cautiously suggested until larger prospective trials confirm the observed results.
