A retrospective assessment of outcomes of chemotherapy-based versus radiation-only adjuvant treatment for completely resected stage I-IV uterine carcinosarcoma

PurposeTo determine the progression-free survival (PFS) and overall survival (OS) in a cohort of patients who received either platinum-based chemotherapy with or without radiation therapy (pelvic or WAI), or RT alone.MethodsMemorial Sloan-Kettering Cancer Center (MSKCC) electronic medical records from 8/1/1995 to 10/3/2007 were reviewed for patient age, diagnosis date, type of primary surgery, residual disease at the completion of primary surgery, FIGO stage, treatment details, dates of progression and death, and site(s) of first recurrence. PFS and OS by stage (I/II v III/IV) and by treatment type (chemotherapy with or without RT v RT alone) were determined using landmark analyses 8 weeks after surgery. Patients who received chemotherapy with or without RT (pelvic or abdominal) or RT alone (pelvic or abdominal) were included in the analysis. Both groups were allowed to have received intravaginal radiation therapy (IVRT).ResultsForty-nine patients met study criteria. Thirty-eight/49 patients received chemotherapy: 23/38 (60.5%) received paclitaxel-carboplatin; 7/38 (18.4%) received ifosfamide-platinum; 8/38 (21.0%) received other chemotherapy. FIGO stage was: I = 15 (31%); II = 5 (10%); III = 21 (43%); IV = 8 (16%). Three-year PFS for the entire cohort was 24%. Three-year OS for the entire cohort was 60%. Three-year median PFS time for the entire cohort was 15 months (95% CI: 11–25 months). Three-year median OS time for the entire cohort was 67 months (95% CI: 23–89 months). Three-year PFS for stages I–II was 43% v 14% for stages III–IV (HR = 1.98 [0.9–4.33]); P = 0.082. Three-year OS for stages I–II was 68% v 55% for stages III–IV (HR = 1.26 [0.47–3.41]); P = 0.648. Three-year PFS for chemotherapy with or without RT was 35% v 9% for RT alone (HR = 1.74 [0.79–3.85]); P = 0.164. Three-year OS for chemotherapy with or without RT was 66% v 34% for RT alone (HR = 2.02 [0.77–5.33]); P = 0.146.ConclusionsOur study corroborates GOG 150 results, and shows that paclitaxel-carboplatin appears to be an efficacious adjuvant chemotherapy regimen for completely resected uterine carcinosarcoma. The role of adjuvant RT in addition to chemotherapy warrants further investigation.     

The effect of maximal surgical cytoreduction on sensitivity to platinum-taxane chemotherapy and subsequent survival in patients with advanced ovarian cancer

ObjectivesLimited information exist about the frequency of micrometastases, their topographic distribution and prognostic impact in patients with cervical carcinoma (CX).MethodsLymph nodes of patients with surgically treated CX, FIGO IB to IIB, with pelvic lymph node involvement, were re-examined regarding the size of metastatic deposits, their topographic distribution within the pelvis. Lymph node status (pN0 vs. pN1mic = metastasis < 0.2 cm vs. pN1 = metastasis > 0.2 cm) was correlated to recurrence free (RFS) and overall survival (OS).Results31.4% of all patients (281/894) represented pelvic lymph node involvement. 22.2.% of the node positive ones showed micrometastases (pN1mic). Most commonly, obturator and internal nodes were affected by pN1mic, without any side differences. Patients with macrometastases (pN1) and micrometastases (pN1mic) represented significant reduced RFS-rate at 5-years (62% [95% CI: 54.2 to 69.8] for pN1 and 68.9% [95% CI: 55.5 to 82.4] for pN1mic) when compared to patients without metastatic disease (91.4% [95% CI: 89.0 to 93.8]; p < 0.001) The 5-years OS-rate was decreased in patients with metastatic disease (pN0: 86.6% [95% CI: 83.7 to 89.5], pN1mic: 63.8% [95% CI: 50.9 to 76.7], pN1: 48.2% [95% CI: 40.4 to 56.0]; p < 0.0001). These differences persisted in detailed analysis within these subgroups. In multivariate analysis, tumor stage, pelvic lymph node involvement and micrometastases were independent prognostic factors.ConclusionsA remarkable number of patients with CX show micrometastases within pelvic nodes. Micrometastatic disease represents an independent prognostic factor. So, all patients with pelvic lymph node involvement, including micrometastatic deposits, might be candidates for adjuvant treatment.     

Surgical and pathologic outcomes of fertility-sparing radical abdominal trachelectomy for FIGO stage IB1 cervical cancer

ObjectivesTo describe the surgical and pathologic findings of fertility-sparing radical abdominal trachelectomy using a standardized surgical technique, and report the rate of post-trachelectomy adjuvant therapy that results in permanent sterility.MethodsA prospectively maintained database of all patients with FIGO stage IB1 cervical cancer admitted to the operating room for planned fertility-sparing radical abdominal trachelectomy was analyzed. Sentinel node mapping was performed via cervical injection of Technetium and blue dye.ResultsBetween 6/2005 and 5/2008, 22 consecutive patients with FIGO stage IB1 cervical cancer underwent laparotomy for planned fertility-sparing radical abdominal trachelectomy. Median age was 33 years (range, 23–43). Histology included 13 (59%) with adenocarcinoma and 9 (41%) with squamous carcinoma. Lymph-vascular invasion was seen in 9 (41%) cases. Only 3 (14%) needed immediate completion radical hysterectomy due to intraoperative findings (2 for positive nodes, 1 for positive endocervical margin). Median number of nodes evaluated was 23 (range, 11–44); and 6 (27%) patients had positive pelvic nodes on final pathology — all received postoperative chemoradiation. Sixteen (73%) patients agreed to participate in sentinel node mapping which yielded a detection rate of 100%, sensitivity of 83%, specificity of 100% and false-negative rate of 17%. Eighteen of 19 (95%) patients who completed trachelectomy had a cerclage placed, and 9/22 (41%) patients had no residual cervical carcinoma on final pathology. Median time in the operating room was 298 min (range, 180–425). Median estimated blood loss was 250 ml (range, 50–700), and median hospital stay was 4 days (range, 3–6). No recurrences were noted at the time of this report.ConclusionsCervical adenocarcinoma and lymph-vascular invasion are common features of patients selected for radical abdominal trachelectomy. The majority of patients can undergo the operation successfully; however, nearly 32% of all selected cases will require hysterectomy or postoperative chemoradiation for oncologic reasons. Sentinel node mapping is useful but until lower false-negative rates are achieved total lymphadenectomy remains the gold standard. Investigating alternative fertility-sparing adjuvant therapy in node positive patients is needed.     

The impact of video-assisted thoracic surgery (VATS) in patients with suspected advanced ovarian malignancies and pleural effusions

OBJECTIVES: We previously reported our initial experience of patients with suspected advanced ovarian cancer and moderate to large pleural effusions who underwent video-assessed thoracic surgery (VATS) before planned abdominal exploration. The objective of this study was to report the surgical findings and management of patients who underwent VATS in an update of our experience. METHODS: We performed a retrospective review of all patients with suspected advanced ovarian cancer and moderate to large pleural effusions who underwent VATS for assessment of extent of intrathoracic disease at our institution between 6/01 and 8/05. RESULTS: Twenty-three patients with a median age of 61 years (range, 36-79) were identified. VATS was performed for right-sided effusions in 17 patients (74%), and a median of 1350 ml (400-3700 ml) of pleural fluid was drained. VATS demonstrated macroscopic disease in 15 (65%) patients, with nodules >1 cm in 11/15 (73%), and nodules <1 cm in 4/15 (27%). Macroscopic intrathoracic disease was found in 4/10 (40%) patients with negative cytology. Intrathoracic cytoreduction was performed in 3/11 patients (27%) with intrathoracic disease >1 cm. After VATS, 12/23 patients (52%) underwent primary surgical management, with cytoreduction to < or =1 cm achieved in 11/12 patients (92%). The other eleven patients received primary chemotherapy after undergoing diagnostic laparoscopy alone (4/11) or no further abdominal exploration (7/11). Nine of these patients proceeded to interval cytoreduction, while 2 had pathology demonstrating upper gastrointestinal and lymphoma primaries at the time of VATS. Final diagnosis of primary site of disease included: ovary, 14 (61%); endometrial, 2 (9%); dual ovarian/endometrial primaries, 1 (4%); fallopian tube, 1 (4%); primary peritoneal, 1 (4%); other, 4 (17%). Overall, findings at VATS altered primary surgical management in 11/23 (48%) patients. CONCLUSIONS: Sixty-five percent of patients with suspected advanced ovarian cancer and moderate to large pleural effusions had gross intrathoracic disease identified at VATS, with the majority (11/15, 73%) having disease >1 cm in diameter. Use of VATS allows for assessment of intrathoracic disease and may help identify candidates for primary cytoreductive surgery and possible intrathoracic cytoreduction versus neoadjuvant chemotherapy.     

Long-term Survival After An Aggressive Surgical Approach in Patients With Breast Cancer Hepatic Metastases

Background: Metastatic breast cancer is generally believed to be associated with a poor prognosis. Therapeutic advances over the past two decades, however, have resulted in improved outcomes for selected patients with limited metastatic disease. Methods: Between March 1991 and October 2002, 31 patients had hepatic resection for breast cancer metastases limited to the liver. Clinical and pathologic data were collected prospectively from breast and hepatobiliary databases. Results: Median age of patients was 46 years (range, 31 to 70). Liver metastases were solitary in 20 patients and multiple in 11 patients. Median size of the largest liver metastasis was 2.9 cm (range, 1 to 8). Major liver resections (three or more segments resected) were performed in 14 patients, whereas minor resections (fewer than three segments resected) with or without radiofrequency ablation (RFA) were performed in 17 patients. No postoperative mortality occurred. Of the 31 patients, 27 (87%) received either preoperative or postoperative systemic therapy as treatment for metastatic disease. The median survival was 63 months; a single patient died within 12 months of hepatic resection. The overall 2- and 5-year survival rates were 86% and 61%, respectively, whereas the 2- and 5-year disease-free survival rates were 39% and 31%, respectively. No treatment- or patient-specific variables were found to correlate with survival rates. Conclusions: In selected patients with liver metastases from breast cancer, an aggressive surgical approach is associated with favorable long-term survival. Hepatic resection should be considered a component of multimodality treatment of breast cancer in these patients.     

An evaluation of stereoacuity (3D vision) in practising surgeons across a range of surgical specialities

BackgroundJudging depth is important in surgery. Although there are several cues that permit depth perception, stereoacuity has been singled out as a possible predictor of surgical ability. However, it is not clear whether high-grade stereoacuity is necessary for a career in surgery. To help answer this, we aimed to evaluate stereoacuities in practising surgeons across a range of surgical specialities.MethodsWe recorded stereoacuity values on 66 surgeons working at a London teaching hospital using three standard stereotests: Titmus, TNO and Frisby. There were 36 Trainees and 30 Consultants, covering 12 surgical specialities.ResultsMedian stereoacuities (with range) for the whole group were: 40 s arc on Titmus (40–800), 30 s arc on TNO (15–480) and 20 s arc on Frisby (20–600). Four surgeons had no recordable stereoacuity on TNO, and one was also unrecordable on Titmus. Three of these four were Consultants. Depending on the test used, high-grade stereopsis was found in 74%–83% of surgeons while reduced stereopsis was found in 2%–14% of surgeons.ConclusionWhile we found that most surgeons in current NHS practice have high-grade stereoacuity, there are also surgeons with reduced stereopsis and some with no stereopsis. The findings do not therefore support the assertion that high-grade stereopsis is a universal requirement for a career in surgery. It would be difficult to justify setting a stereoacuity criterion for entrance into a surgical training programme.
