Optimal (≤1 cm) but visible residual disease: is extensive debulking warranted?

OBJECTIVES: To determine if extensive upper abdominal surgery (UAS) affected overall survival (OS) in patients left with ≤ 1 cm but visible residual disease after undergoing primary cytoreductive surgery for ovarian cancer. Our secondary objective was to determine if leaving ≤ 1cm but visible residual throughout the small bowel (SB) conferred a worse prognosis. METHODS: All stage IIIB-IV ovarian cancer patients who had visible but ≤ 1 cm residual disease at time of primary cytoreductive surgery from 2001 to 2010 were identified. Extensive UAS procedures and residual SB involvement were recorded. RESULTS: The 219 patients identified with ≤1 cm but visible residual disease had a median OS of 51 months. In this cohort, 127 had extensive UAS performed, and 87 had residual disease involving the SB. Univariate OS analysis was performed. There was no significant difference in OS between patients who did or did not have extensive UAS (45 vs. 52 months, P=0.56), or between patients with or without residual SB disease (45 vs. 51 months, P=0.84). Factors that were significantly associated with OS were age, ASA score, family history, and stage. CONCLUSIONS: Patients cytoreduced to ≤ 1 cm but visible residual disease who required UAS did not have a worse OS than those who did not require UAS. OS was similar if residual disease involved the SB or not. For ovarian cancer patients with disease not amenable to complete gross resection, extensive surgery should still be considered to achieve ≤ 1 cm but visible residual disease status, including cases where the residual disease involves the SB.

Positive peritoneal cytology is highly predictive of prognosis and relapse patterns in stage III (FIGO 2009) endometrial cancer.

OBJECTIVES: According to the updated FIGO system, positive peritoneal cytology does not affect endometrial cancer stage. This revision may reduce rates of obtaining cytology, with unclear implications in advanced disease. This study evaluates the significance of positive cytology in stage III (FIGO 2009) endometrial cancer. METHODS: Eligible patients received treatment for stage III endometrial cancer at a single institution and had peritoneal cytology performed. RESULTS: Of 196 patients, 58% were ≥ 60 years old, 48% had deep myometrial invasion, 71% lymphovascular invasion, 25% cervical invasion, 37% adnexal involvement, 79% nodal involvement, and 46% aggressive histology. Positive cytology was present in 23% (45/196) and significantly associated with cervical stromal invasion, adnexal involvement, and aggressive histology (P ≤ 0.03). There was no significant difference in rates of lymphadenectomy, chemotherapy, or radiation between negative and positive cytology groups. At a median follow-up of 47 months, the 5-year freedom from relapse was 39% for positive cytology vs. 69% for negative, disease-specific survival 42% vs. 77%, and overall survival 34% vs. 72% (P < 0.001). Positive cytology correlated with higher recurrence rates in the para-aortic nodes and peritoneum (30% vs. 9%, 23% vs. 4%; P ≤ 0.008). When controlling for adverse features including aggressive histology, positive cytology was associated with an increased hazard for relapse (HR 2.3; P = 0.002) and death (HR 2.9; P < 0.001). CONCLUSIONS: In stage III endometrial cancer, positive cytology independently predicts outcome and is associated with distinct relapse patterns. Obtaining peritoneal cytology in stage III endometrial cancer is critical.

Impact of incorporating an algorithm that utilizes sentinel lymph node mapping during minimally invasive procedures on the detection of stage IIIC endometrial cancer.

OBJECTIVE: To determine whether the frequency of cases diagnosed with stage IIIC endometrial cancer is affected by the incorporation of a modified surgical lymph node assessment. METHODS: Since 2008, we have increasingly utilized a modified nodal assessment using an algorithm that incorporates SLN mapping. For this analysis, we identified all cases of newly diagnosed endometrial cancers undergoing a minimally invasive staging procedure not requiring conversion to laparotomy from 1/1/08 to 12/31/10. Procedures were categorized as standard, modified, and hysterectomy only. Differences were based on time period: 2008 (Y1), 2009 (Y2), and 2010 (Y3). Appropriate statistical tests were used. RESULTS: We identified a total of 507 cases. The distribution of cases was 143 (Y1), 190 (Y2), and 174 (Y3). Tumor grade (P=0.05) and high-risk histologies (P=0.8) did not differ during the 3 time periods. A standard staging procedure was performed in the following cases: Y1 (93/143; 65%), Y2 (66/166; 35%), and Y3 (40/164; 23%) (P<0.001). Median operative times were as follows: Y1 (218 min), Y2 (198 min), and Y3 (176.5 min) (P<0.001). The median numbers of total lymph nodes removed among cases with at least 1 node retrieved were: Y1 (20); Y2 (10); Y3 (7) (P<0.001). Cases diagnosed as stage IIIC were as follows: Y1 (10/143; 7%), Y2 (15/166; 7.9%), and Y3 (13/164; 7.5%) (P=1.0). CONCLUSIONS: The incorporation of a modified staging approach utilizing the SLN mapping algorithm reduces the need for standard lymphadenectomy and does not appear to adversely affect the rate of stage IIIC detection.

Anterior pelvic exenteration with total vaginectomy for recurrent or persistent genitourinary malignancies: review of surgical technique, complications, and outcome.

OBJECTIVE: To describe the surgical technique, complications, and outcomes after anterior pelvic exenteration with total vaginectomy (AETV) for recurrent or persistent genitourinary malignancies. METHODS: We reviewed the medical records of all patients who underwent AETV between 12/2002 and 07/2011. Relevant demographic, clinical, and pathological information was collected. Postoperative complications and rates of readmission and reoperation (up to 180 days after surgery) were examined, and preliminary survival data were obtained. RESULTS: We identified 11 patients who underwent AETV. The median age at the time of the surgery was 55 years (range, 36-71). The median tumor size was 0.9 cm (range, microscopic - 4). Primary tumor sites included: cervix, 6; uterus, 3; vagina, 1; and urethra, 1. Complete surgical resection with negative pathologic margins was achieved in all 11 patients. Major postoperative complications occurred in 4 patients (36%). Six patients (55%) required readmission to the hospital. No operative mortalities were observed, and none of the patients required a re-operation. With a median follow-up after the procedure of 25 months (range, 6-95), none of the patients developed a pelvic recurrence. Ten patients (91%) were alive without evidence of disease and one patient (9%) developed a pancreatic recurrence. CONCLUSION: AETV sparing the rectosigmoid and anus is feasible in highly selected patients with central pelvic recurrences. Compared to previously reported studies on total pelvic exenteration, data from this case series suggest that AETV may be associated with a lower rate of complications without compromising the oncologic outcome, while also preserving rectal function.

Reproductive outcomes of patients undergoing radical trachelectomy for early-stage cervical cancer.

OBJECTIVE: To report the reproductive outcomes of patients undergoing fertility-preserving radical trachelectomy (RT) for the treatment of early-stage cervical cancer. METHODS: We analyzed data from our institution's first 105 patients who underwent attempted fertility-sparing surgery with radical trachelectomy, pelvic lymphadenectomy, and cerclage from November 2001 to October 2010. RESULTS: Of the 105 patients who underwent attempted RT, 77 (73%) did not require a conversion to radical hysterectomy or postoperative treatment. The median age was 32 (range, 25-38 years). Most patients (75%) had stage IB1 disease. Sixty-six patients (63%) were nulliparous. Thirty-five women were actively attempting conception 6 months after surgery, and 23 (66%) women were successful in conceiving: there were 20 live births, 3 elective terminations, and 4 spontaneous miscarriages. Four patients had 2 pregnancies each; all delivered their second pregnancy between 32 and 36 weeks. Cerclage erosion through the vaginal wall occurred in 6 cases and was treated by transvaginal removal of protruding suture material. One of these patients experienced a second trimester miscarriage. CONCLUSIONS: The majority of women who attempted to conceive after radical trachelectomy were successful, and most of their pregnancies resulted in full-term births. Assisted reproduction played an important role in select women. Cerclage likely contributed to a post-trachelectomy uterine ability to carry a pregnancy to the third trimester. The second post-trachelectomy pregnancy appears to be at higher risk for preterm delivery than the first pregnancy.

Extended pelvic resections for recurrent or persistent uterine and cervical malignancies: an update on out of the box surgery.

OBJECTIVE: To update our report on the outcome of patients who underwent extended pelvic resection (EPR) for recurrent or persistent uterine and cervical malignancies. METHODS: We reviewed the records of all patients who underwent EPR between 6/2000 and 07/2011. EPR was defined as an en-bloc resection of a pelvic tumor with sidewall muscle, bone, major nerve, and/or major vascular structure. Complications up to 180 days post surgery were analyzed. Survivals were estimated using the Kaplan-Meier method. RESULTS: We identified 22 patients. Median age at the time of EPR was 58 years (range, 36-74). Median tumor diameter was 5.4 cm (range, 1.5-11.2). Primary tumor sites included: uterus, 13; cervix, 7; synchronous uterus/cervix, 1; and synchronous uterus/ovary, 1. The EPR structures were: muscle, 13; nerve, 10; bone, 8; vessel, 5. Complete gross resection with microscopically negative margins (R0 resection) was achieved in 17 patients (77%). There were no perioperative mortalities. Major postoperative complications occurred in 14 patients (64%). The two most common morbidities were pelvic abscesses and peripheral neuropathies. Median follow-up time was 28 months (range, 6-99). The 5-year overall survival (OS) for the entire cohort was 34% (95% CI, 13-57). For the 17 patients who had an R0 resection, the 5-year OS was 48% (95% CI, 19-73). In patients with positive pathologic margins (n=5), the 5-year OS was 0%. CONCLUSION: EPR was associated with prolonged survival when an R0 resection was achieved. The high rate of postoperative complications remains a hallmark of these procedures and properly selected patients should be extensively counseled preoperatively.

Accuracy of frozen section diagnosis of ovarian borderline tumor.

OBJECTIVE: The objective of this study was to determine the incidence of invasive cancer in ovarian masses diagnosed as borderline tumor (BT) at the time of frozen section. METHODS: We performed a retrospective review of all patients diagnosed with ovarian BT on frozen section (FS) at our institution between 2000 and 2010. Clinical and pathologic data were extracted. Univariate and multivariate analyses were performed using standard two-sided statistical tests. RESULTS: A total of 120 patients were identified, of which 104 (86.7%) had BT on frozen section that was confirmed on final pathology. In 15 (12.5%) patients, BT was diagnosed on FS but was reclassified as invasive cancer on final pathology. One patient (0.8%) had BT on FS but benign pathology on final diagnosis. Histologies included serous in 79 (65.8%), seromucinous in 13 (10.8%), mucinous in 21 (17.5), endometrioid in 5 (4.2%), and clear cell in 2 (1.7%) patients. Reclassification of pathologic diagnosis was related to histologic subtype, but only for endometrioid and clear cell tumors (P<0.001). The rate of invasive cancer for serous micropapillary tumors on frozen section was 42.8% compared with 2.8% for serous non-micropapillary tumors (P<0.001). Tumor size >8 cm was associated with a 22.4% incidence of invasive cancer on final pathology compared to 3.2% in tumors ≤ 8 cm (P=0.004). CONCLUSION: Comprehensive surgical staging can be considered in BT >8 cm in diameter, as well as those with micropapillary serous, endometrioid, and clear cell histology diagnosed at the time of frozen section analysis.

Clinicopathologic significance of DNA mismatch repair protein defects and endometrial cancer in women 40years of age and younger.

BACKGROUND: The hereditary basis of endometrial cancer is apparent in young women with endometrial cancer. The objective of this study was to examine risk factors and outcomes in patients 40 years of age and younger with endometrial cancer. METHODS: We performed a retrospective cohort study of patients aged 40 years or less who were diagnosed with endometrial carcinoma between 1/93 and 5/08. Clinical and pathologic data were extracted from medical records. Paraffin-embedded slides from hysterectomy specimens were obtained and DNA mismatch repair (MMR) immunohistochemistry was performed. Cases were analyzed according to the presence of DNA MMR protein defects. Standard two-sided statistical tests were performed. RESULTS: Of the 56 identified patients, the median age was 36 years (range, 24-40). The majority of the endometrial carcinomas were of endometrioid histology (91%), stage I (71%), and FIGO grade 1 (59%). Abnormal DNA MMR was found in 9 cases (16%). Cases with abnormal DNA MMR had lower body mass index (BMI) (P=0.05), and had a family history suggestive of Lynch syndrome (P=0.001). Tumors were more likely to have advanced stage disease (P<0.001), be high grade (P<0.001), have deep myometrial invasion (P<0.001), and have lymphovascular invasion (P=0.002). Cases with abnormal DNA MMR had significantly worse overall survival (P=0.028) and progression-free survival (P=0.042). CONCLUSIONS: Endometrial cancer is rare in women aged 40 years or less. In this group of patients, loss of DNA MMR was associated with lower BMI, worse clinicopathologic factors, and worse outcome. These results may have implications when young women diagnosed with endometrial cancer are counseled regarding prognosis.

Surgical cytoreduction in stage IV endometrioid endometrial carcinoma.

OBJECTIVE: To evaluate the role of surgical cytoreduction and the amount of residual disease in patients with newly diagnosed stage IV endometrioid endometrial carcinoma (EC). METHODS: Patients with stage IV EC of endometrioid histology who underwent surgery at our institution from 1977 to 2003 were identified. Patients with microscopic stage IV disease were excluded. Progression-free survival (PFS) and overall survival (OS) were estimated using Kaplan Meier method and compared with log-rank test. RESULTS: A total of 58 patients were identified, of which 9 (15.5%) had no gross residual (NGR) after surgery, 11 (19.0%) had residual disease ≤1 cm, 32 (55.1%) had residual disease >1 cm, and 6 (10.3%) had no cytoreduction attempted. The median PFS was 11.1 months (95% CI, 9.8-12.3) and the median OS was 19.2 months (95% CI, 8.5-29.9) for the cohort. The median PFS was 40.3 months (95% CI, 0-93.9) for patients with NGR disease, 11 months (95% CI, 9.9-12.1) for patients with any residual disease, and 2.2 months (95% CI, 0.1-4.2) for patients who did not have attempted cytoreduction (P<0.001). The median OS was 42.2 months (95% CI, not estimable) for patients with NGR disease, 19 months (95% CI, 13.9-24.1) for patients with any residual disease, and 2.2 months (95% CI, 0.1-4.2) for patients that did not have attempted cytoreduction (P<0.001). CONCLUSION: Though stage IV endometrioid EC has a poor prognosis, surgical cytoreduction to no gross residual disease in a highly select group of patients is associated with improved survival.

Sentinel lymph node mapping for endometrial cancer improves the detection of metastatic disease to regional lymph nodes.

OBJECTIVE: To compare the incidence of metastatic cancer cells in sentinel lymph nodes (SLN) vs. non-sentinel nodes in patients who had lymphatic mapping for endometrial cancer and to determine the contribution of metastases detected on ultrastaging to the overall nodal metastasis rate. METHODS: All patients who underwent lymphatic mapping for endometrial cancer were reviewed. Cervical injection of blue dye was used in all cases. Sentinel nodes were examined by routine hematoxylin and eosin (H&E), and if negative, by standardized institutional pathology protocol that included additional sections and immunohistochemistry (IHC). RESULTS: Between 09/2005 and 03/2010, 266 patients with endometrial cancer underwent lymphatic mapping. Sentinel node identification was successful in 223 (84%) cases. Positive nodes were diagnosed in 32/266 (12%) patients. Of those, 8/266 patients (3%) had the metastasis detected only by additional section or IHC as part of SLN ultrastaging. Excluding the 8 cases with positive SLN on ultrastaging only, 24/801 (2.99%) SLN and 30/2698 (1.11%) non-SLN were positive for metastatic disease (p=0.0003). CONCLUSION: Using a cervical injection for mapping, metastatic cells from endometrial cancer are three times as likely to be detected in SLN than in the non-sentinel nodes. This finding strongly supports the concept of lymphatic mapping in endometrial cancer to fine tune the nodal dissection topography. By adding SLN mapping to our current surgical staging procedures we may increase the likelihood of detecting metastatic cancer cells in regional lymph nodes. An additional benefit of incorporating pathologic ultrastaging of SLN is the detection of micrometastasis, which may be the only evidence of extrauterine spread.

Survival in epithelial ovarian cancer: a multivariate analysis incorporating BRCA mutation status and platinum sensitivity.

BACKGROUND: Patients with BRCA-associated ovarian cancer (OC) have a survival advantage over those with sporadic OC. To further explore this, we examined the impact of prognostic factors on disease-free survival (DFS) and overall survival (OS) in patients with known BRCA mutation status. PATIENTS AND METHODS: We reviewed stage III-IV OC patients treated at our institution between 1 December 1996 and 30 September 2006 and also tested on protocol for BRCA mutations. Impact on DFS and OS was determined by Kaplan-Meier analysis and a Cox proportional hazards model. RESULTS: Of the 110 patients, 36 had deleterious BRCA mutations [BRCA (+)] and 74 were BRCA wild type [BRCA(-)]. Thirty-one of 36 (86%) BRCA (+) and 60 of 74 (81%) BRCA (-) patients were platinum sensitive (P = 0.60). Median OS was longer for BRCA (+) patients (not reached versus 67.8 months; P = 0.02), but DFS was similar (26.9 versus 24.0, P = 0.3). On multivariate analysis, OS correlated with primary platinum sensitivity [HR = 0.15; 95% CI (confidence interval) 0.06-0.34] and BRCA (+) mutation status (HR = 0.33; 95% CI 0.12-0.86). CONCLUSIONS: BRCA mutation status predicted OS independent of primary platinum sensitivity, suggesting that underlying tumor biology contributes to disease outcome and may be worthy of consideration in future clinical trial design.

Risk factors for recurrence of ovarian borderline tumors.

OBJECTIVE: The objective of this study was to identify clinicopathologic features that are associated with an increased risk of recurrence for borderline ovarian tumors (BOT). METHODS: We performed a retrospective review of all patients treated for BOT at our institution from 1979 to 2008. Progression-free survival (PFS) was defined as the time of diagnosis to time of recurrence/death or last follow-up. The Kaplan-Meier method was used to calculate the PFS rate and the Wilcoxon-Gehan test was performed to identify prognostic factors. RESULTS: A total of 266 patients were identified. The median age was 43 years (range, 15-94 years). The majority of patients (68.4%) had FIGO stage I disease and serous histology (73.7%). Only 23 (8.6%) patients developed recurrent disease. The median PFS was 19 years and the median follow-up was 4 years. Abnormal baseline CA-125 (>35 U/ml), advanced stage, age at diagnosis, and invasive implants were associated with decreased PFS. Of the 196 patients with serous BOT, those with a micropapillary pattern had a 3-year PFS of 75.9% (95%CI, 55.6-87.8) compared with 94.3% (95% CI, 88.4-97.3) for patients without micropapillary pattern (P<0.001). CONCLUSION: Age at diagnosis, an elevated preoperative CA-125, invasive implants, and micropapillary histology were clinical factors associated with increased risk of recurrence in women with BOT. Including these clinicopathologic features will likely identify patients at higher risk for recurrence, for whom development of new treatment strategies would be appropriate.

Tertiary cytoreduction in patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer: an updated series.

OBJECTIVE: Surgical cytoreduction is an integral therapeutic modality for patients with epithelial ovarian (EOC), fallopian tube (FTC), or primary peritoneal (PPC) cancer in the primary setting. The role of surgical cytoreduction in the recurrent setting is not clearly defined and remains controversial. The objective of this study was to assess this potential survival benefit in a large cohort of patients with a long follow-up period. METHODS: We performed a retrospective chart review of all patients with recurrent EOC, FTC, or PPC who underwent tertiary cytoreduction at our institution from 2/98 to 2/08. Disease-specific survival (DSS) was calculated from the time of tertiary cytoreduction to death or last follow-up. Univariate and multivariate analyses were used to analyze outcomes and to identify potential prognostic factors. RESULTS: A total of 77 patients were identified, of which 38 (49%) have died of disease. The median time from secondary to tertiary cytoreduction was 25.7 months (range, 4.1-99.4 months). The median follow-up after tertiary cytoreduction was 28.9 months (range, 0.7-123.7 months), with a median DSS for the entire cohort of 47.7 months (95% CI, 25.5-69.9 months). On univariate analysis, residual disease after tertiary cytoreduction and TFI were found to be significant prognostic factors. On multivariate analysis, only residual disease after tertiary cytoreduction retained prognostic significance (P<0.001). CONCLUSION: Tertiary surgical cytoreduction may offer a survival benefit in a highly select group of patients with recurrent EOC, FTC, or PPC. This benefit appears to be greatest in patients in whom a complete gross resection can be achieved.

Beyond tertiary cytoreduction in patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer.

BACKGROUND: Primary, secondary, and possibly tertiary surgical cytoreduction in patients with recurrent epithelial ovarian (EOC), fallopian tube (FTC), or primary peritoneal (PPC) cancer appears to be associated with a survival benefit. The objective of this study was to assess if cytoreduction of recurrences after tertiary cytoreduction offers any potential benefit in these patients. METHODS: We performed a retrospective chart review of all patients with recurrent EOC, FTC, or PPC who underwent additional cytoreductive procedures after a prior tertiary cytoreduction (quaternary cytoreduction) at our institution between 1991 and 2008. Disease-specific survival (DSS) was calculated from the time of quaternary cytoreduction to last follow-up. Univariate analyses were used to analyze outcomes and to identify potential prognostic factors. RESULTS: A total of 15 patients were identified, of which 7 (47%) have died of disease. All patients had undergone prior optimal secondary and tertiary surgical cytoreductive procedures. The size of residual disease varied from 0 (in 10 cases/67%) to >1 cm (in 2 cases, 13%). Residual disease (1 cm) and number of recurrence sites (single vs multiple) were found to be significant prognostic factors on univariate analysis. CONCLUSIONS: Cytoreductive surgery beyond tertiary cytoreduction may be a reasonable option in highly select patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer, especially in the setting of a single site of recurrent disease.

A nomogram for predicting overall survival of women with endometrial cancer following primary therapy: toward improving individualized cancer care.

OBJECTIVES: Traditionally we have relied mainly on final FIGO stage to estimate overall oncologic outcome in endometrial cancer patients. However, it is well known that other patient factors may play equally important roles in outcome. Our objective was to develop a clinically useful nomogram in the hope of providing a more individualized and accurate estimation of overall survival (OS) following primary therapy. METHODS: Using a prospectively maintained endometrial cancer database, 1735 patients treated between 1993 and 2008 were analyzed. Characteristics known to predict OS were collected. For each patient, points were assigned to each of these 5 variables. A total score was calculated. The association between each predictor and the outcome was assessed by multivariable modeling. The corresponding 3-year OS probabilities were then determined from the nomogram. RESULTS: The median age was 62 years (range, 25-96). Final grade included: G1 (471), G2 (622), G3 (634), and missing (8). Stage included: IA (501), IB (590), IC (141), IIA (36), IIB (75), IIIA (116), IIIB (6), IIIC (135), IVA (7), and IVB (128). Histology included: adenocarcinoma (1376), carcinosarcoma (100), clear cell (62), and serous (197). Median follow-up for survivors was 29.2 months (0-162.2 months). Concordance probability estimator for the nomogram is 0.746+/-0.011. CONCLUSION: We developed a nomogram based on 5 easily available clinical characteristics to predict OS with a high concordance probability. This nomogram incorporates other individualized patient variables beyond FIGO stage to more accurately predict outcome. This new tool may be useful to clinicians in assessing patient risk when deciding on follow-up strategies.

The incidence of pelvic lymph node metastasis by FIGO staging for patients with adequately surgically staged endometrial adenocarcinoma of endometrioid histology.

The seminal Gynecologic Oncology Group study on surgical pathologic spread patterns of endometrial cancer demonstrated the risk of pelvic lymph node metastasis for clinical stage I endometrial cancer based on tumor grade and thirds of myometrial invasion. However, the FIGO staging system assigns surgical stage by categorizing depth of myometrial invasion in halves. The objective of this study was to determine the incidence of pelvic lymph node metastasis in endometrial cancer based on tumor grade and myometrial invasion as per the current FIGO staging system. We reviewed the records of all patients who underwent primary surgical staging for clinical stage I endometrial cancer at our institution between May 1993 and November 2005. To make the study cohort as homogeneous as possible, we included only cases of endometrioid histology. We also included only patients who had adequate staging, which was defined as a total hysterectomy with removal of at least eight pelvic lymph nodes. During the study period, 1036 patients underwent primary surgery for endometrial cancer. The study cohort was composed of the 349 patients who met study inclusion criteria. Distribution of tumor grade was as follows: grade 1, 80 (23%); grade 2, 182 (52%); and grade 3, 87 (25%). Overall, 30 patients (9%) had pelvic lymph node metastasis. The incidence of pelvic lymph node metastasis in relation to tumor grade and depth of myometrial invasion (none, inner half, and outer half) was as follows: grade 1-0%, 0%, and 0%, respectively; grade 2-4%, 10%, and 17%, respectively; and grade 3-0%, 7%, and 28%, respectively. We determined the incidence of pelvic nodal metastasis in a large cohort of endometrial cancer patients of uniform histologic subtype in relation to tumor grade and a one-half myometrial invasion cutoff. These data are more applicable to current surgical practice than the previously described one-third myometrial invasion cutoff results.

Extended pelvic resections for recurrent uterine and cervical cancer: out-of-the-box surgery.

Patients with recurrent uterine and cervical cancer have poor prognoses. The objective of this study was to analyze the outcomes of patients with recurrent uterine and cervical cancer who had undergone attempted curative resection of pelvic bone, sidewall muscle, major blood vessels, and/or nerves. We reviewed the records of all 14 patients with recurrent uterine and cervical cancer who had extended pelvic resections at our institution between June 2000 and November 2006. Primary sites of disease were the uterus (11 patients) and cervix (3 patients). Tumor histology was as follows: adenocarcinoma, seven; squamous cell carcinoma, three; leiomyosarcoma, three; and adenosarcoma, one. Previous treatment included hysterectomy, 11; pelvic radiation, 9; chemotherapy, 9; and total pelvic exenteration, 2. Extended pelvic resections included removal of pelvic sidewall muscle, five; bone, five; common and/or external iliac vessel, five; femoral nerve, two; lumbosacral nerve root, one; and obturator nerve, one. Other procedures included total pelvic exenteration, three; posterior exenteration, two; and anterior exenteration, one. Complete resection with negative margins was obtained in 11 (78%) of 14 patients. Seven patients (50%) received high-dose rate intraoperative radiation therapy. Reconstructive procedures included continent or incontinent urinary diversion, four; femoral-femoral arterial bypass, two; myocutaneous flap, two; and urinary ileal interposition, one. Median total operating time was 628 min (range, 345-935 min) and median estimated blood loss was 900 mL (range, 300-16,000 mL). Seven patients (50%) had one or more major complication(s), including pelvic abscess, three; colonic fistula, two; massive intraoperative hemorrhage, one; postoperative bladder perforation, one; thrombosed femoral-femoral graft, one; and disruption of appendicocutaneous urinary anastomosis, one. At a median follow-up of 26 months (range, 5-84 months), ten patients (71%) are alive and four patients (29%) have died of disease at 8, 13, 33, and 42 months postoperatively.

Management of uterine malignancy found incidentally after supracervical hysterectomy or uterine morcellation for presumed benign disease.

Patients who have undergone supracervical hysterectomy or uterine morcellation for presumed benign uterine disease and are found to have malignancy on final pathology represent a management dilemma. Our goal was to analyze our experience and make observations regarding staging, treatment, and outcomes. We performed a retrospective case series of patients referred to our institution with uterine malignancy who previously underwent supracervical hysterectomy or uterine morcellation at the time of original surgery for presumed benign uterine disease. Between January 2000 and March 2006, 17 patients with uterine malignancy were identified. Following initial surgery, 15 (88%) patients had presumed stage I disease and 2 (12%) patients had stage III disease. Two (15%) of 13 patients who underwent completion surgery were upstaged; both had leiomyosarcoma (LMS) originally resected with morcellation. Ten of 11 patients whose stage was confirmed with secondary surgery remain disease free. None of the patients who initially underwent supracervical hysterectomy without morcellation were upstaged by secondary surgery. The median follow-up interval was 30 months (range, 2-90 months). Reoperation for completion surgery and staging is important when uterine malignancy is found incidentally after morcellation or supracervical hysterectomy for presumed benign uterine disease. Approximately 15% of patients will be upstaged by reexploration, particularly those with LMS who underwent morcellation. Patients who undergo completion surgery with restaging and are not upstaged appear to have a good prognosis. Surgical staging is valuable for prognosis and may alter postoperative treatments.

Initial experience with Dargent's operation: the radical vaginal trachelectomy.

OBJECTIVE: To report on our initial experience with radical vaginal trachelectomy for patients with early-stage cervical cancer. METHODS: Data on patients undergoing radical vaginal trachelectomy with pelvic lymphadenectomy from 11/01 to 12/06 were collected in a prospective database. RESULTS: Forty-three women with early-stage cervical cancer were operated on with the intent of fertility preservation with radical vaginal trachelectomy. Median age was 31 years (range, 20-40 years). FIGO stage for the group was: IB1, 28; IA2, 7; IA1 with lymphovascular invasion, 8. Histologic type included: squamous, 24; adenocarcinoma, 16; adenosquamous, 3. Parity for the group was: nullipara, 35; one child, 7; two children, 1. Median BMI was 24 kg/m2 (range, 19-42 kg/m2). Two patients (5%) underwent completion hysterectomy due to extensive endocervical disease. The median OR time was 330 min (range, 220-480 min). Median pelvic lymph node count was 25 (range, 9-52). Median hospital stay was 3 days (range, 3-7 days). Four patients (9%) required a second intervention for a perioperative complication. Five patients (12%) underwent adjuvant chemoradiation for pathologic risk factors determined on final pathology. Eleven (79%) of 14 women who were trying to get pregnant were able to conceive. Four (36%) required assisted reproductive techniques to conceive. Four patients delivered by cesarean section after 35 weeks and four patients are currently pregnant. With a median follow-up of 21 months in patients treated with trachelectomy alone, we have had one recurrence. CONCLUSIONS: Radical vaginal trachelectomy can be incorporated into gynecologic oncology practices and appears to be a reasonable option for patients with early cervical cancer who desire to maintain their fertility. It should be discussed with candidate patients during preoperative consultation.

Resection of recurrent cervical cancer after total pelvic exenteration.

The objective of this study was to describe the management of patients with recurrent cervical cancer after total pelvic exenteration (TPE). We reviewed the records of patients who underwent TPE for recurrent cervical cancer between June 1992 and December 2003 and subsequently developed recurrent disease. Thirty-seven patients underwent TPE during the study period, and 25 (68%) subsequently developed recurrence proven by radiographic and/or biopsy studies. Recurrence sites included pelvic (12), inguinal (5), retroperitoneal (5), hepatic (4), vulva (2), perineum (1), transposed ovary (1), and lung (1). The median time to recurrence was 7 months (range 2-73 months), with 92% (23/25) occurring within 2 years of TPE. Management of recurrence was known in 21 of 25 patients, which included chemotherapy (10), surgical resection (7), and no further treatment (4). Surgically resected recurrences were isolated to the groin (2), vulva (2), perineum (1), transposed ovary (1), and psoas muscle (1). The four patients who underwent ovarian, perineal, and vulvar resections succumbed to their disease in a median time of 13 months (range 2-21 months). Of the two patients with surgically resected groin recurrences, one is alive with disease 21 months after initial recurrence and the other is alive without evidence of disease 85 months later. One patient had an isolated 4-cm recurrence involving the psoas muscle and the femoral nerve and is without the evidence of disease 9 months later. Resection of isolated recurrences after TPE is a reasonable option in selected patients, particularly in those with solitary inguinal metastases.
