RESUMEN

OBJECTIVE: We sought to describe clinicopathologic and treatment factors associated with oncologic outcomes in patients with early-stage ovarian clear cell carcinoma undergoing complete staging and in a sub-set of these patients undergoing fertility-conserving surgery. METHODS: We retrospectively identified patients with ovarian clear cell carcinoma initially treated at our institution from January 1, 1996 to March 31, 2020. Survival was estimated using Kaplan-Meier curves and compared by log-rank test. Survival-associated variables were identified by Cox proportional hazards regression. RESULTS: Of 182 patients, mismatch repair and p53 protein expression were assessed by immunohistochemistry on 82 and 66 samples, respectively. There were no significant differences in progression-free survival or overall survival between mismatch repair-deficient (n=6, including 4 patients with Lynch syndrome; 7.3%) and mismatch repair-proficient patients, whereas aberrant p53 expression (n=3; 4.5%) was associated with worse progression-free (p<0.001) and overall survival (p=0.01). Patients with stage IA/IC1 disease had a 95% 5-year overall survival rate (95% CI 88% to 98%); patients with stage IC2/IC3 disease had a similar 5-year overall survival rate (76%; 95% CI 54% to 88%) to that of patients with stage IIA/IIB disease (82%; 95% CI 54% to 94%). There was no difference in 5-year overall survival in patients with stage IA/IC1 undergoing chemotherapy versus observation (94% vs 100%). Nine patients underwent fertility-sparing surgery and none experienced recurrence. Of five patients who pursued fertility, all had successful pregnancies. CONCLUSIONS: In patients with completely staged ovarian clear cell carcinoma, those with stage IA/IC1 disease have an excellent prognosis, regardless of chemotherapy. Aberrant p53 expression may portend worse outcomes. Additional investigation is warranted on the safety of fertility conservation in patients with stage IA/IC1 disease.

RESUMEN

INTRODUCTION: Delays from primary surgery to chemotherapy are associated with worse survival in ovarian cancer, however the impact of delays from neoadjuvant chemotherapy to interval debulking surgery is unknown. We sought to evaluate the association of delays from neoadjuvant chemotherapy to interval debulking with survival. METHODS: Patients with a diagnosis of stage III/IV ovarian cancer receiving neoadjuvant chemotherapy from July 2015 to December 2017 were included in our analysis. Delays from neoadjuvant chemotherapy to interval debulking were defined as time from last preoperative carboplatin to interval debulking >6 weeks. Fisher's exact/Wilcoxon rank sum tests were used to compare clinical characteristics. The Kaplan-Meier method, log-rank test, and multivariate Cox Proportional-Hazards models were used to estimate progression-free and overall survival and examine differences by delay groups, adjusting for covariates. RESULTS: Of the 224 women, 159 (71%) underwent interval debulking and 34 (21%) of these experienced delays from neoadjuvant chemotherapy to interval debulking. These women were older (median 68 vs 65 years, P=0.05) and received more preoperative chemotherapy cycles (median 6 vs 4, P=0.003). Delays from neoadjuvant chemotherapy to interval debulking were associated with worse overall survival (HR 2.4 95% CI 1.2 to 4.8, P=0.01), however survival was not significantly shortened after adjusting for age, stage, and complete gross resection, HR 1.66 95% CI 0.8 to 3.4, P=0.17. Delays from neoadjuvant chemotherapy to interval debulking were not associated with worse progression-free survival (HR 1.55 95% CI 0.97 to 2.5, P=0.062). Increase in number of preoperative cycles (P=0.005) and lack of complete gross resection (P<0.001) were the only variables predictive of worse progression-free survival. DISCUSSION: Delays from neoadjuvant chemotherapy to interval debulking were not associated with worse overall survival after adjustment for age, stage, and complete gross resection.

RESUMEN

OBJECTIVES: To assess outcomes and patterns of recurrence in patients with high-grade serous ovarian/tubal/primary peritoneal cancers with radiographic supraclavicular lymphadenopathy at diagnosis. METHODS: We evaluated all patients with newly diagnosed high-grade serous ovarian cancers treated at our center between January 1, 2008 and May 1, 2013 who had supraclavicular lymphadenopathy (defined as ≥1 cm in short axis) on radiographic imaging (either computed tomography or positron emission tomography) at the time of diagnosis. RESULTS: Of 586 patients with high-grade serous ovarian cancer receiving primary treatment during the study period, we identified 13 (2.2%) with supraclavicular lymphadenopathy diagnosed on pre-treatment imaging. The median age at diagnosis was 52.0 years (range 38.2-72.3). Five (31%) had clinically palpable nodes on physical examination. Four (31%) had a known BRCA mutation. All 13 patients underwent neoadjuvant chemotherapy, followed by interval debulking surgery. Each patient received a median of four cycles of neoadjuvant intravenous chemotherapy (range 3-7). At interval debulking surgery, complete gross resection was achieved in nine (70%) patients, and optimal resection (0.1-1 cm residual disease) in four (30%). Eleven patients (85%) recurred; however, only one (8%) recurred in the supraclavicular lymph nodes. Median follow-up time was 44.3 months (range 22.4-95.0). Median progression-free survival for the cohort was 11.7 months (95% CI 9.2 to 14.1). Median overall survival was 44.3 months (95% CI 41.5 to 47.1). In patients obtaining complete gross resection at interval debulking surgery, median progression-free survival and overall survival were 13.9 months (95% CI 8.9 to 18.9) and 78.1 months (95% CI 11.1 to 145.1), respectively. CONCLUSIONS: In our study, approximately 2% of patients with high-grade serous ovarian cancer presented with radiographic evidence of supraclavicular lymphadenopathy. Supraclavicular lymphadenopathy at diagnosis did not portend an unfavorable outcome when complete gross resection was achieved at interval debulking surgery.

RESUMEN

OBJECTIVE: As our understanding of sentinel lymph node (SLN) mapping for endometrial cancer (EC) evolves, tailoring the technique to individual patients at high risk for failed mapping may result in a higher rate of successful bilateral mapping (SBM). The study objective is to identify patient, tumor, and surgeon factors associated with successful SBM in patients with EC and complex atypical hyperplasia (CAH). METHODS: From September 2012 to November 2014, women with EC or CAH underwent SLN mapping via cervical injection followed by robot-assisted total laparoscopic hysterectomy (RA-TLH) at a tertiary care academic center. Completion lymphadenectomy and ultrastaging were performed according to an institutional protocol. Patient demographics, tumor and surgeon/intraoperative variables were prospectively collected and analyzed. Univariate and multivariate analyses were performed evaluating factors known or hypothesized to impact the rate of successful lymphatic mapping. RESULTS: RA-TLH and SLN mapping was performed in 111 women; 93 had EC and 18 had CAH. Eighty women had low grade and 31 had high grade disease. Overall, at least one SLN was identified in 85.6% of patients with SBM in 62.2% of patients. Dye choice (indocyanine green versus isosulfan blue), odds ratio (OR: 4.5), body mass index (OR: 0.95), and clinically enlarged lymph nodes (OR: 0.24) were associated with SBM rate on multivariate analyses. The use of indocyanine green dye was particularly beneficial in patients with a body mass index greater than 30. CONCLUSION: Injection dye, BMI, and clinically enlarged lymph nodes are important considerations when performing sentinel lymph node mapping for EC.

RESUMEN

OBJECTIVE: Primary cytoreductive surgery in patients with stage IIIC-IV epithelial ovarian cancer frequently includes diaphragm peritonectomy or resection, which can lead to symptomatic pleural effusions when the resection specimen is ≥ 10 cm. Our objective was to evaluate whether the placement of an intraoperative thoracostomy tube decreased the incidence of symptomatic pleural effusions in these cases. METHODS: We identified 156 patients who underwent primary debulking surgery involving diaphragm peritonectomy or resection for stage III-IV ovarian cancer from 1/01-12/09. Using standard statistical tests, the incidence of symptomatic pleural effusions and other variables were compared between patients who did and did not have intraoperative chest tubes placed. RESULTS: Forty-nine patients had a resected diaphragm specimen ≥ 10 cm in largest dimension; 28 (57%) did not undergo chest tube placement (NCT group) while 21 (43%) did (CT group). Mediastinal lymph node dissection (0% vs 19%, P = 0.028) and liver resections (11% vs 38%, P = 0.037) were higher in the CT group. Postoperatively, 57% of the NCT group developed a moderate or large pleural effusion compared to 19% of the CT group (P = 0.007). Thirteen patients (46%) in the NCT group developed respiratory symptoms requiring either placement of a postoperative chest tube or thoracentesis compared to 3 patients (14%) in the CT group (P = 0.018). CONCLUSIONS: Diaphragm peritonectomy or resection can often lead to moderate or large pleural effusions that may become symptomatic. In these patients, intraoperative chest tube placement may be considered to decrease the incidence of symptomatic effusions and the need for postoperative chest tube placement or thoracentesis.

RESUMEN

OBJECTIVE: The purpose of this study was to evaluate the significance of parenchymal splenic metastasis (PSM) in ovarian (OC), fallopian tube (FTC), and primary peritoneal cancer (PPC). METHODS: All patients with stage IIIB-IV OC, FTC, and PPC undergoing primary cytoreduction from 2001 to 2010 at our institution were identified. In patients undergoing splenectomy, pathology was reviewed for the presence of PSM. Multivariate Cox regression and Kaplan-Meier survival analysis were used to evaluate factors associated with overall survival (OS). RESULTS: Of 576 patients identified, stage was: IIIB - 23 (4%), IIIC - 468 (81.2%), and IV - 85 (14.8%). Optimal cytoreduction was achieved in 430 patients (74.7%), including 85 of 97 patients (87.6%) undergoing splenectomy. PSM was identified in 20 patients (20.6%) undergoing splenectomy, including 3 of 5 patients (60%) with radiographically identified parenchymal liver metastases and 17 of 92 patients (18.5%) without such radiographic findings (P=0.059). Age, preoperative albumin, residual disease, stage, bulky upper abdominal disease, IP chemotherapy, and PSM were associated with OS on univariate analysis. Splenectomy was not associated with survival. Age, preoperative albumin, residual disease, stage, and PSM (HR=0.46; 95% CI, 0.27-0.77) were associated with OS on multivariate analysis. In the subset of patients undergoing splenectomy, OS was lower for patients with PSM versus those without PSM (28.5 v 51.2months, P=0.004). CONCLUSIONS: PSM is independently associated with decreased OS in patients with advanced OC, FTC, and PPC. PSM occurs in the setting of other evidence of hematogenously disseminated disease, but also occurs outside this setting. PSM should be considered a criterion for stage IV disease.

RESUMEN

OBJECTIVE: The objective of this study was to evaluate the risk factors and potential morbidity associated with intraoperative hypothermia (IH) during cytoreductive surgery (CRS) for advanced ovarian cancer. METHODS: Demographic and perioperative data were collected for all patients with stage IIIC-IV ovarian, fallopian tube, and primary peritoneal carcinoma who underwent primary CRS at our institution from 2001 to 2010. Only patients with carcinomatosis and/or bulky upper abdominal disease and residual disease of <1cm were included. Intraoperative hypothermia was defined as temperature of <36.0 degrees Celsius (°C). Associations with 21 perioperative factors, 12 systems-based complications, and specific complications including but not limited to venous thromboembolism and surgical site infection were evaluated. RESULTS: Two hundred ninety-seven patients met the inclusion criteria. An intraoperative temperature <36°C was noted in 72.1% of patients, and a temperature <36°C at the time of abdominal closure was noted in 45.5%. Intraoperative vasopressors (P=0.02), epidural anesthesia (P=0.01), transfusion of fresh frozen plasma (P<0.05), and blood loss (P=0.01) were associated with IH. There was no association between IH and postoperative complications in general (P=0.48) or specifically grade 3-5 complications (P=0.34). Univariate analysis did show an association between hematologic complications and IH; however, this did not persist on multivariate analysis (P=0.14). CONCLUSIONS: In patients who underwent optimal primary CRS for advanced ovarian cancer, IH alone was not associated with the development of postoperative complications. Postoperative morbidity in these patients is multifactorial and further investigation into modifiable risk factors is warranted.

RESUMEN

OBJECTIVES: To evaluate patterns of recurrence in 1988 FIGO stage IC endometrioid endometrial adenocarcinoma. METHODS: A prospectively maintained endometrial cancer database was utilized to identify all patients with stage IC endometrioid endometrial adenocarcinoma treated between 2/93 and 6/09. Patterns of recurrence and risk factors were analyzed. RESULTS: One hundred thirty-four patients with stage IC endometrial cancer were identified. Median age was 66 years (range, 31-91 years). All patients were initially treated surgically, and 79% underwent comprehensive surgical staging with lymphadenectomy. Median number of lymph nodes removed was 18 (range, 1-45). Fifty-one patients (38%) had FIGO grade 1 tumors, 55 (41%) had grade 2 tumors, and 28 (21%) had grade 3 tumors. The majority of patients (91%) received adjuvant radiation therapy. With a median follow-up of 36 months (range, 0.6-141.4 months), 10 patients recurred. Of these, 2 (20%) were grade 1, 2 (20%) were grade 2, and 6 (60%) were grade 3. Nine (90%) of these recurrences had a distant component and 7 (70%) were fatal. Overall, the 3 year cumulative incidence failure rate for grade 1/2 tumors was 5.4%; for grade 3 tumors it was 28.9% (P<0.001). Age, BMI, and lymphovascular invasion were not associated with an increased risk of recurrence. CONCLUSIONS: Patients with stage IC, grade 3 endometrial cancer had a significantly increased risk of recurrence (28.9%). All of these recurrences had a distant component and the majority were fatal. Further investigation into the addition of adjuvant systemic therapy in these high-risk patients is warranted.

RESUMEN

OBJECTIVE: BRCA-associated and sporadic ovarian cancers have different pathologic and clinical features. Our goal was to determine if BRCA mutation status is an independent predictor of residual tumor volume following primary surgical cytoreduction. METHODS: We conducted a retrospective analysis of patients with FIGO stage IIIC-IV high-grade serous ovarian cancer classified for the presence or absence of germline BRCA mutations. The primary outcome was tumor-debulking status categorized as complete gross resection (0mm), optimal but visible disease (1-10 mm), or suboptimal debulking (>10 mm) following primary surgical cytoreduction. Overall survival by residual tumor size and BRCA status was also assessed as a secondary endpoint. RESULTS: Data from 367 patients (69 BRCA mutated, 298 BRCA wild-type) were analyzed. Rate of optimal tumor debulking (0-10 mm) in BRCA wild-type and BRCA-mutated patients were 70.1% and 84.1%, respectively (P=0.02). On univariate analysis, increasing age (10-year OR, 1.33; 95% CI, 1.07-1.65; P=0.01) and wild-type BRCA status (OR, 0.47; 95% CI, 0.23-0.94, P=0.03) were both significantly associated with suboptimal surgical outcome. On multivariate analysis, BRCA mutation status was no longer associated with residual tumor volume (OR, 0.63; 95% CI, 0.31-1.29; P=0.21) while age remained a borderline significant predictor (10-year OR, 1.25; 95% CI, 1.01-1.56; P=0.05). Both smaller residual tumor volume and mutant BRCA status were significantly associated with improved overall survival. CONCLUSION: BRCA mutation status is not associated with the rate of optimal tumor debulking at primary surgery after accounting for differences in patient age. Improved survival of BRCA carriers is unlikely the result of better surgical outcomes but instead intrinsic tumor biology.

RESUMEN

OBJECTIVES: To evaluate the impact of operative start time (OST) on surgical outcomes in patients with advanced ovarian cancer. METHODS: All stage IIIB-IV serous ovarian cancer patients who underwent primary surgery at our institution from 1/01 to 1/10 were identified. Fourteen factors were evaluated for an association with surgical outcomes including OST and OR tumor index (1 point each for carcinomatosis and/or bulky [≥ 1 cm] upper abdominal disease). Univariate logistic regression considering within-surgeon clustering was performed for cytoreduction to ≤ 1 cm versus >1cm residual disease. In patients with ≤ 1 cm residual disease, univariate logistic regression considering within-surgeon clustering was performed for 1-10mm residual disease versus complete gross resection (CGR, 0mm residual). A multivariate logistic model was developed based on univariate analysis results in the ≤ 1 cm residual disease cohort. RESULTS: Of 422 patients, residual disease was: 0mm, 144 (34.1%); 1-10mm, 175 (41.5%); >10mm, 103 (23.3%). OST was not associated with cytoreduction to ≤ 1 cm residual disease on univariate analysis. In the ≤ 1 cm residual disease cohort, albumin, CA-125, ascites, ASA score, stage, OR tumor index, and OST were associated with CGR on univariate analysis. Earlier OSTs were associated with increased rates of CGR. On multivariate analysis, CA-125 was independently associated with CGR. OST was associated with CGR in patients with an OR tumor index of 2 but not an OR tumor index<2. CONCLUSIONS: OST was not associated with cytoreduction to ≤ 1 cm residual disease in patients with advanced serous ovarian cancer. In the cohort of patients with ≤ 1 cm residual disease, later OSTs were associated with reduced rates of CGR in patients with greater tumor burden.

RESUMEN

PURPOSE OF REVIEW: This review will focus on the implications of BRCA status in the patient with high-grade serous ovarian cancer, the differences between BRCA1 and BRCA2 mutations, and the most effective risk-reducing strategies. RECENT FINDINGS: Women with BRCA-associated epithelial ovarian cancer represent a unique group who commonly are diagnosed at a younger age, have advanced high-grade serous disease, have improved sensitivity to platinum-based chemotherapy in both the upfront and recurrent setting, and have an overall improved prognosis. Promising novel therapeutic agents such as poly (ADP-ribose) polymerase inhibitors have increased activity in patients with inherited BRCA mutations and may also have a role in patients with noninherited tumors that have decreased BRCA activity. Risk-reducing salpingo-oophorectomy (RRSO) is effective in decreasing risks of both breast and gynecologic cancer in women with BRCA mutations. However, when counseling women at inherited risk, the inherent phenotypical differences between BRCA1 and BRCA2 mutations must be considered. SUMMARY: Patients with BRCA-associated epithelial ovarian cancer have improved response to platinum-based chemotherapy, improved survival, and may be appropriate candidates for treatment with novel targeted therapies. RRSO remains the most effective risk-reduction strategy in women with BRCA mutations.

RESUMEN

GOALS: Gynecologic cancers represent a significant proportion of malignancies affecting women. Historically, cancer treatment focused primarily on eradicating disease, irrespective of the impact on fertility. The implementation of early detection protocols and advanced treatment regimens has resulted in improved prognosis for gynecologic cancer patients. With this improvement, more attention is now paid to quality-of-life issues. Fertility preservation (FP) has become an integral component in the selection and execution of gynecological cancer management. In this report we address gynecologic malignancies as they relate to future fertility potential. METHODS: We review reproductive principles such as ovarian reserve, uterine function, cervical competence, and early obstetrical management, as well as available FP methods. In addition, we discuss the potential damage that cancer and cancer treatments can impart on the female reproductive system. We offer general recommendations regarding baseline screening tests useful in assessing the feasibility of FP. Lastly, cancer-specific FP methods are presented. RESULTS: Oocyte quantity and quality naturally decline with advancing age. In most patients, the slope of decline steepens significantly after the age of 35. Reliable ovarian reserve measures exist and should be utilized to assess and triage potential candidates for FP. Advancements in FP, particularly in oocyte cryopreservation (OC), have improved the success rates associated with the techniques available to cancer patients. Currently, where successfully available, OC appears to be the preferred method for single women diagnosed with a gynecologic malignancy as it affords reproductive autonomy, whereas embryo cryopreservation using a donor gamete remains an alternative. CONCLUSIONS: In gynecologic oncology, effective treatments to achieve cancer survival can compromise the ability to subsequently conceive and/or carry a child. Therefore, as the field of oncofertility continues to expand, a discussion regarding FP should be initiated when tailoring a cancer treatment protocol.

RESUMEN

OBJECTIVES: To evaluate the incidence and risk factors for ventral hernia development following primary laparotomy for ovarian, fallopian tube, and peritoneal cancers. METHODS: All patients who underwent primary laparotomy for ovarian, tubal, or peritoneal cancer from 3/05 to 12/07 were identified. Hernias were identified radiographically or during physical exam. One-year and 2-year hernia rates were calculated. Clinicopathologic factors were evaluated for an association with the development of hernia using univariate and multivariate analysis. RESULTS: We identified 239 cases with 12 months of follow-up. Median age was 60 years (17-89 years), and median body mass index (BMI) was 25.0 kg/m(2) (16.9-58.5 kg/m(2)). Advanced stage disease (FIGO stage III/IV) was diagnosed in 182/239 (76%). The 1-year hernia rate was 8.8% (21/239): 13/21 (61.9%) were symptomatic, and 8/21 (38.1%) underwent hernia repair operations. On multivariate analysis, only BMI (p=0.004) and intraperitoneal (IP) chemotherapy (p=0.016) retained their independent association with hernia development by 12 months. Of the 239 patients, 167 had 24 months of follow-up. The 2-year hernia rate was 23.4% (39/167): 25/39 (64.1%) were symptomatic, and 17/39 (43.6%) underwent hernia repair operations. Multivariate analysis in this group demonstrated that advanced stage (p=0.033), wound complications (p=0.029), and BMI (p=0.012) were independently associated with hernia development by 24 months. CONCLUSIONS: The development of ventral hernia is a significant postoperative morbidity in patients undergoing primary surgery for ovarian, tubal, or peritoneal cancer. Independent associations with hernia development include: BMI and IP chemotherapy by Year 1, and BMI, wound complications and advanced stage by Year 2.

RESUMEN

OBJECTIVE: We have previously shown that lysophosphatidic acid (LPA) promotes the ovarian cancer metastatic cascade. In this study, we evaluated the role of LPA on endometrial cancer invasion. METHODS: Transient mRNA knockdown was accomplished using pre-designed siRNA duplexes against LPA receptor 2 (LPA2) and human matrix metalloproteinase-7 (MMP-7). RT-PCR was used to characterize LPA receptor and MMP-7 expression. Analysis of in vitro invasion was performed with rat-tail collagen type I coated Boyden chambers. Gelatin zymography was used to evaluate the MMP activity in cell culture conditioned media. Cell-cell and cell-matrix attachment was also assessed upon LPA2 knockdown to further illuminate the LPA2 cascade. RESULTS: LPA increases HEC1A cellular invasion at physiologic concentrations (0.1-1 muM). Of the four principle LPA receptors, LPA2 is predominantly expressed by HEC1A cells. Transient transfection of LPA2 siRNA reduced LPA2 mRNA expression in HEC1A cells by 93% (P<0.01). Silencing LPA2 eliminated the LPA-stimulated increase in invasion (P<0.05) and reduced LPA-induced MMP-7 secretion/activation, without significantly affecting cell-cell or cell-matrix adhesion. Silencing MMP-7 reduced overall invasion but did not eliminate LPA's pro-invasive effect on HEC1A cells, as compared to negative control (P<0.05). Gelatin zymography confirmed that LPA2 and MMP-7 knockdown reduced MMP-7 activation in HEC1A conditioned media. CONCLUSION: LPA2 mediates LPA-stimulated HEC1A invasion and the subsequent activation of MMP-7.

RESUMEN

OBJECTIVE: The purpose of this study was to assess the vascular indices generated by 3-dimensional (3D) power Doppler angiography by evaluating the cyclic changes in the vascularity of normal ovaries, including those that were ovulating, nonovulating, and hormonally suppressed. METHODS: In this prospective longitudinal observational study, a cohort of premenopausal regularly menstruating women with no known ovarian disease underwent 3D power Doppler imaging every 2 to 3 days for the duration of 1 menstrual cycle. Four indices were generated: vascularization index (VI), flow index (FI), vascularization-flow index (VFI), and mean grayness. Comparisons of vascularity were made between ovulating, nonovulating, and hormonally suppressed ovaries. Normal ranges were established and graphed longitudinally. RESULTS: Eighteen participants (36 ovaries) ages 28 to 45 years underwent an average of 10 examinations, yielding 368 acquired ovarian volumes for analysis. Seven participants used hormonal contraception. The VI, FI, and VFI were closely correlated (Pearson product moment correlation coefficients, 0.52-0.95). The vascular indices of ovulating ovaries were significantly higher than those of nonovulating ovaries (VI, FI, and VFI, all P < .001), with the largest discrepancies during the luteal phase. Hormonally suppressed ovaries had significantly lower vascularity throughout the cycle (VI, P < .002; FI, P < .001; VFI, P < .007). The vascular indices of all groups appeared to drop during the late follicular period and then rise again. CONCLUSIONS: The VI would suffice as the principal vascular parameter for 3D power Doppler analysis. Preovulatory scans may be more useful for distinguishing pathologic vascularization. Hormonally suppressed ovaries have significantly lower vascularity throughout the cycle. Normal-appearing ovaries with vascular indices above the normal ranges established by these data may warrant further investigation.

RESUMEN

This content presents pathology of the cervix and vulva - its diagnosis, staging, treatment, and prognosis. The authors distinguish between the clinical staging of cervical cancer and the surgical staging of vulvar cancer and note advances in surgical, medical, and radiation oncology in the treatment of both cervical and vulvar carcinoma that allow for individualization of patient treatment resulting in improved oncologic outcomes and improved quality of life. Treatment algorithms are presented based on the varying stages at which the cancer is diagnosed.
