Thinking Twice about the Cervical Mass: A Case Report of Primary Vaginal Leiomyosarcoma and Review of the Literature

Primary vaginal leiomyosarcoma (LMS) is an unusual cause of aggressive gynecologic cancer which requires prompt surgical treatment for favorable outcomes. Definitive diagnosis and treatment render unique challenges to clinicians based on vague presentation and limited evidence for management. Here, we describe a case of vaginal LMS in a middle-aged woman with a history of cervical dysplasia found to have a proximal vaginal mass after presenting with vaginal discharge and cramping pain. The patient was diagnosed on pathologic surgical specimen and subsequently underwent definitive surgical treatment. She remains with no evidence of disease 20 months later. In our report, we emphasize the nuances of surgical management including localized source control in those desiring future fertility. Ultimately, we make recommendations for surgical treatment and surveillance based on the available published literature.

Laparoscopic predictability of minimally invasive interval debulking in advanced ovarian cancer: The MIID-SOC trial

BACKGROUND

We sought to create a laparoscopic-based model to predict the ability to perform a minimally invasive (MIS) cytoreductive surgery in advanced epithelial ovarian cancer patients who have received neoadjuvant chemotherapy (NACT).

METHODS

Fifty women were enrolled in a multi-institutional prospective pilot study (NCT03378128). Each patient underwent laparoscopic evaluation of 43 abdominopelvic sites followed by surgeon dictated surgical approach, either continue MIS or laparotomically. However, if the procedure continued MIS, the placement of a hand-assist port for manual palpation was mandated to emulate a laparotomic approach and all 43 sites were re-evaluated. Sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy were calculated for each site to predict MIS resectability. Each parameter was assigned a numeric value based on the strength of statistical association and a total predictive index score (PIV) was assigned for each patient. Receiver operating characteristic curve analysis was used to assess the ability of the model to predict the MIS approach.

RESULTS

Twenty-seven patients (61%) underwent MIS surgery. The following abdominopelvic sites were selected for inclusion in the model: gastrosplenic ligament, rectum, left mesocolon, transverse colon, right colon, cecum, appendix, liver capsule, intrahepatic fossa/gallbladder, ileum/jejunum. Using the PIV, a ROC was generated with an AUC = 0.695. In the final model, a PIV <2 identified patients able to undergo an optimal MIS cytoreductive surgery with an accuracy of 68.2%. The specificity, or the ability to identify patients who would not be able to undergo an optimal MIS interval cytoreductive surgery, was 66.7%.

CONCLUSION

This predictive index model may help to guide future inclusion criteria in randomized studies evaluating the MIS approach in advanced epithelial ovarian cancer.

Efficacy of hyperthermic intraperitoneal chemotherapy and interval debulking surgery in women with advanced uterine serous carcinoma

•

In this small series, HIPEC is well tolerated in patients with advanced USC.

•

HIPEC at IDS is associated with favorable PFS and OS in advanced USC.

•

Further investigation of HIPEC in women with advanced USC is warranted.

Objective(s)

To investigate the efficacy and safety of hyperthermic intraperitoneal chemotherapy (HIPEC) at the time of iterval debulking surgery (IDS) in women with advanced uterine serous carcinoma (USC) following neoadjuvant chemotherapy (NACT).

Methods

An IRB-approved single-institution prospective registry was queried to identify women with incidentally identified USC at the time of IDS + HIPEC for high-grade serous carcinoma. Patient demographic, oncologic, and surgical outcomes data were recorded. Univariate analysis determined progression-free survival (PFS) and overall survival (OS).

Results

In total, seven patients were found to have advanced USC after undergoing IDS + HIPEC, with a median age of 64.5 years. The majority had stage IV, (n = 6, 85.7%), MMR proficient (n = 5, 71.4%), p53 mutant (n = 6, 85.1%) USC. The median pre-operative CA125 was 24.0U/mL. HIPEC regimen was cisplatin (n = 3, 42.9%) or cisplatin with paclitaxel (n = 4, 57.1%). All patients underwent optimal cytoreduction, with 71.4% (n = 5) having no gross residual disease. Accordion post-operative complications were mild in 14.3% (n = 1), moderate in 57.1% (n = 4) and severe in 14.3% (n = 1); 14.3% (n = 1) had no complications. The median length of stay was 6.5 days (IQR 4–8 days) with a median time to chemotherapy of 33.0 days. The median PFS was 14.0 months (95% CI 3.5–20.8 months), and the median OS was 27.0 months (95% CI 5.1- not reached).

Conclusions

In this small, prospective series, we demonstrate that IDS + HIPEC is well tolerated in patients with USC and is associated with favorable PFS and OS following NACT. Further prospective investigation is needed to validate these promising findings in larger, heterogeneous cohorts of women with advanced USC who are not candidates for primary surgical management.

Anastomotic leak following interval debulking surgery with or without hyperthermic intraperitoneal chemotherapy in women with advanced epithelial ovarian Cancer

OBJECTIVE(S)

To evaluate the incidence and associated risk factors for anastomotic failure following interval debulking surgery (IDS) with or without hyperthermic intraperitoneal chemotherapy (HIPEC) in women with advanced ovarian cancer.

METHODS

We performed a retrospective cohort study in women with stage III/IV high-grade ovarian cancer treated with neoadjuvant chemotherapy followed by IDS with colorectal resection and HIPEC from 2017 to 2020. These patients were compared to a historical control cohort who underwent IDS with colorectal resection without HIPEC from 2009 to 2016. Data was collected for demographics, surgical variables, and perioperative outcomes. The univariate analysis compared progression-free survival and overall survival.

RESULTS

61 women were identified; 21 (34.4%) underwent IDS with HIPEC from 2017 to 2020, and 40 underwent IDS alone from 2009 to 2016. None of the patients who had IDS with HIPEC had protective ileostomy, compared to 10.0% of those who received had IDS alone (n = 4)(p = 0.29). The cumulative incidence of anastomotic leak rate was 8.2% (n = 5). There was no significant difference in anastomotic leak rate for women who underwent IDS with HIPEC (9.5%, n = 2) versus without HIPEC (7.5%, n = 3) (p = 0.99). While there was no difference in PFS (12.2 vs. 13.3 months, log-rank p = 0.31), OS (9.4 vs. 40.6 months, log-rank p = 0.013) was significantly decreased following postoperative anastomotic leak.

CONCLUSIONS

In this retrospective series of women with advanced ovarian cancer, HIPEC was not associated with increased risk for anastomotic leak at the time of IDS with colorectal resection and reanastomosis. While further study is needed, HIPEC alone should not preclude colorectal resection or dictate practices for colonic diversion in IDS.

Modified frailty index predicts postoperative complications in women with gynecologic cancer undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

OBJECTIVE(S)

To evaluate the impact of frailty on postoperative complications following cytoreductive surgery (CRS) with hyperthermic intra-peritoneal chemotherapy (HIPEC) in women with advanced or recurrent gynecologic cancer.

METHODS

An IRB-approved single-institution prospective registry was queried for women who underwent CRS with HIPEC for advanced or recurrent gynecologic cancer from 1/1/2014-12/31/2020. Frailty was defined as a modified Frailty Index (mFI) score of ≥2. Logistic regression was used to assess the impact of mFI upon the rate of moderate or higher (≥ grade 2) Accordion postoperative complications.

RESULTS

Of 141 women, 81.6% (n = 115) were non-frail with mFI of 0-1 and 18.4% (n = 26) were frail with mFI ≥2. The incidence of ≥ grade 2 complications was 21.2% (n = 14) for mFI = 0, 26.5% (n = 13) for mFI = 1, 64.7% (n = 11) for mFI = 2 and 100.0% (n = 9) for patients with mFI ≥3. The incidence of re-operation (1.7% vs. 11.5%, p = 0.044), ICU admission (13.2% vs. 34.6%, p = 0.018), acute kidney injury (6.3% vs. 30.8%, p = 0.001), and respiratory failure (0.9% vs. 19.2%, p < 0.001) were significantly lower amongst non-frail vs. frail women. On multivariable analysis, mFI ≥2 was associated with significantly increased ≥ grade 2 complications versus mFI of 0-1 (OR 9.4, 95% CI 3.3, 26.4, p < 0.001). Age (OR 1.04, 95% CI 1.00, 1.09, p = 0.07), surgical indication (recurrent vs. primary) (OR 0.71, 95% CI 0.30, 1.7, p = 0.44) and Surgical Complexity Score of Intermediate or High vs. Low (OR 1.5, 95% CI 0.67, 3.5, p = 0.31) were not associated with ≥grade 2 complications.

CONCLUSIONS

Frailty, defined by the modified frailty index, is predictive of ≥grade 2 postoperative complications following CRS with HIPEC in women with gynecologic cancer. Frailty screening before CRS with HIPEC may assist patient selection and improve postoperative outcomes.

Perioperative outcomes of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy in elderly women with epithelial ovarian cancer: analysis of a prospective registry

OBJECTIVE

To evaluate perioperative outcomes in elderly versus non-elderly women with advanced or recurrent epithelial ovarian cancer undergoing surgery with hyperthermic intraperitoneal chemotherapy (HIPEC).

METHODS

A single-institution prospective registry was analyzed for women with ovarian cancer who underwent surgery with HIPEC from January 2014 to December 2020. Elderly age was defined as ≥65 years at surgery. Complications were defined according to the Accordion scale. Univariate and multivariable analysis was used to compare progression-free survival and overall survival.

RESULTS

Of 127 women who underwent surgery with HIPEC, 33.1% (n=42) were ≥65 and 17.3% (n=22) were ≥70 years old. The median age for non-elderly and elderly patients were 55.7±8.3 versus 72.0±5.4 years, respectively (p<0.001). The majority of non-elderly versus elderly patients underwent HIPEC at the time of interval cytoreductive surgery following neoadjuvant chemotherapy (52.9% vs 73.8%, p=0.024). There were no differences in moderate (15.3% vs 26.2%) or severe postoperative complications (10.6% vs 11.9%, p=0.08), acute kidney injury (7.1% vs 16.7%, p=0.12), and length of stay (5.0 vs 5.0 days, p=0.56) for non-elderly versus elderly patients. With a median follow-up of 20 months (95% CI 9.1 to 32.7 months), there was no difference in progression-free survival (18.8 vs 15.7 months, p=0.75) or overall survival (61.6 months vs not estimable, p=0.72) for non-elderly versus elderly patients. Comparing patients 65-69 versus ≥70 years, progression-free survival (33.0 vs 12.5 months, p=0.002) was significantly improved in patients aged 65-69, without difference in overall survival (not estimable vs 36.0 months, p=0.91). On multivariable analysis, age ≥65 did not impact progression-free survival (p=0.74).

CONCLUSIONS

In this prospective registry of women with ovarian cancer, perioperative morbidity is not increased for non-elderly versus elderly patients following surgery with HIPEC. While age should not exclude patients from surgery with HIPEC, additional research is needed regarding oncologic benefits in elderly women.

Patterns of recurrence in women with advanced and recurrent epithelial ovarian cancer treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy

OBJECTIVE(S)

To identify recurrence patterns and outcomes in women with advanced or recurrent epithelial ovarian cancer (EOC) after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC).

METHODS

This is an IRB-approved single-institution cohort study of women who underwent CRS+HIPEC for advanced or recurrent EOC followed in a prospective registry from 1/12/2014-3/1/2020. Recurrence locations were defined as pelvic, upper abdominal (UA) and/or extra-peritoneal (EP). Univariate analysis assessed associations between recurrence location, progression-free survival (PFS), and overall survival (OS).

RESULTS

In total, 92 women with EOC underwent interval (56.5%; n=52) or recurrent CRS+HIPEC (43.5%; n=40). For interval CRS+HIPEC, recurrence locations were pelvic in 50.0% (n=15), UA in 23.3% (n=7) and EP in 56.7% (n=17); 40.0% (n=12) were EP alone. Similarly, for recurrent CRS+HIPEC, recurrence locations were pelvic (22.5%, n=9), UA (5.0%, n=2) and EP (60.0%, n=24); 66.7% (n=20) were EP alone. For both interval and recurrent CRS+HIPEC, median PFS was 10.5 vs. 13.0 months for pelvic and UA vs. EP only recurrences (p=0.02). Similarly, median OS was 29.2 months for pelvic and UA and not reached for EP only (p=0.05). For interval CRS+HIPEC, there was no difference in median PFS (10.6 vs. 11.7 months, p=0.68) and OS (27.1 vs. 24.8 months, p=0.96) for pelvic and UA vs EP alone. However, for recurrent CRS+HIPEC, pelvic and UA sites of recurrence were associated with reduced PFS (10.0 vs. 18.1 months, p=0.03) and OS (33.6 months vs. not reached, p=0.02) vs. EP only.

CONCLUSIONS

In women with advanced or recurrent EOC undergoing CRS+HIPEC, one-half of patients experience their first recurrence outside of the peritoneal cavity. Providers must be aware of the risk of EP failure in patients treated with CRS+HIPEC.

Impact of intra-operative factors upon peri-operative outcomes in women undergoing hyperthermic intraperitoneal chemotherapy for gynecologic cancer

OBJECTIVES

To evaluate the incidence of intra-operative metabolic and electrolyte abnormalities and subsequent impact on peri-operative outcomes in women with gynecologic cancer undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS + HIPEC).

METHODS

An IRB-approved single institution retrospective cohort study was performed in women with gynecologic cancer who underwent CRS + HIPEC. Patient demographics, intra-operative electrolyte and metabolic values and peri-operative outcomes were recorded. To assess the association of pH and lactate upon post-operative outcomes, patients were divided in four quartiles for both variables and univariate analysis was performed.

RESULTS

100 consecutive women who underwent CRS + HIPEC from 2017 to 2020 were identified. Intra-operative blood transfusion and pressor support were required in 40% and 86%, respectively. The rate of ICU admission was 17%. Longer operative time (7.0 vs. 5.3 h, p = 0.002), increased blood loss (400.0 vs. 200.0 mL, p = 0.02) and transfusion (70.6% vs. 34.1%, p = 0.005) were associated with ICU admission. Compared to patients in the highest quartile of pH, lower median pH, (7.211 vs. 7.349, p < 0.001) was associated with increased rates of ICU admission, prolonged intubation (36.0% vs. 0.0%, p < 0.05, respectively) and any post-operative complication (72.0% vs. 28.0%, p = 0.01). Similarly, need for prolonged intubation (40% vs. 0%, p = 0.04) and VTE (13.0% vs. 0%, p = 0.01) were increased in women with the highest quartile of lactate levels compared to the lowest (4.7 vs 1.9, p < 0.001).

CONCLUSIONS

Intra-operative acidosis is associated with higher incidence of ICU admission and peri-operative complications following CRS + HIPEC in women with gynecologic cancer. These data support the importance of adequate intra-operative resuscitation and timely correction of hemodynamic and metabolic abnormalities.

Assessing feasibility and perioperative outcomes with minimally invasive surgery compared with laparotomy for interval debulking surgery with hyperthermic intraperitoneal chemotherapy for advanced epithelial ovarian cancer

Objective

To determine peri-operative outcomes in women with advanced epithelial ovarian cancer (EOC) undergoing interval debulking surgery (IDS) with hyperthermic intraperitoneal chemotherapy (HIPEC) via minimally invasive interval debulking surgery (MIS) or laparotomy (LAP).

Methods

A single institution, retrospective cohort study was performed in women with EOC who underwent IDS with HIPEC from 2017 to 2019 via MIS or LAP. Peri-operative outcomes were compared using univariate analysis.

Results

In total, 50 eligible women were identified; ten (20.0%) underwent MIS + HIPEC and 40 (80.0%) LAP + HIPEC. The median age of patients in the MIS group was 71.1 vs. 64.2 years in LAP (p = 0.031). There was no significant difference in pre-operative complete radiographic response following NACT (p = 0.18). Notably, there was no difference in the rate of R0 resection (70.0% vs. 77.5%; p = 0.39). There was no significant difference in ICU admission, estimated blood loss, operative time, or use of vasopressors between the cohorts. Similarly, there was no difference in 30-day adverse events for MIS vs. LAP, but length of stay was decreased for those who underwent minimally invasive procedures (3 vs. 4 days, p = 0.016). Time to initiation of chemotherapy following surgery was not significantly different between groups (26.2 days vs 32.0 days, p = 0.090). With median follow-up of 15.1 months, there was no difference in recurrence free survival (median 15.0 vs 17.2 months log-rank, p = 0.30) for MIS vs. LAP.

Conclusions

In this retrospective cohort study, we demonstrate that in women with advanced EOC, HIPEC with MIS at the time of IDS following NACT is feasible. Our institutional experience demonstrates similar rates of R0 cytoreduction, compared to LAP. An MIS approach should not prevent surgeons from utilizing HIPEC where indicated for management of advanced EOC.

•

When comparing MIS and LAP at time of HIPEC, no differences are observed in adverse perioperative outcomes.

•

MIS was associated with shorter hospitalization and with no significant difference in the rate of R0 resections.

•

Patient candidacy for an MIS IDS should not prevent surgeons from utilizing HIPEC in appropriate candidates.

Characterizing the efficacy and trends of adjuvant therapy versus observation in women with early stage (uterine confined) leiomyosarcoma: a National Cancer Database study

Objective

The utility of adjuvant therapy for women with uterine confined leiomyosarcoma remains uncertain. We sought to identify trends, analyze efficacy, and assess survival impact of adjuvant therapy in this patients.

Methods

We performed an observational cohort study of 1030 women with early stage leiomyosarcoma from the 2008–2014 National Cancer Database. Multi-nominal logistic regression was used to identify trends in receipt of adjuvant treatment. Demographic and clinical characteristics were compared. Kaplan-Meier curves were used to estimate survival.

Results

There were 547 who (53.1%) received observation, 79 (7.7%) received radiation alone, 340 (33.0%) received chemotherapy alone, and 64 (6.2%) received chemoradiation. Patients were more likely to be observed if tumor size was <5 cm (hazard ratio [HR]=0.97; 95% confidence interval [CI]=0.95–0.99; p=0.017) and less likely to be observed if lymphovascular space invasion (LVSI) was present (HR=0.60; 95% CI=0.41–0.89; p=0.010). Patients were more likely to receive chemotherapy if they were younger (HR=0.78; 95% CI=0.65–0.94; p=0.010) and if they had LVSI (HR=1.47; 95% CI=1.01–2.16; p=0.040). There was an independent association between older age, tumor size >5 cm, and LVSI with worsened survival, with the strongest predictor of mortality being the presence of LVSI. With a median survival of 61.9 months, there was no difference in estimated overall survival at 1 and 3 years based on receipt of adjuvant treatment as compared to observation (p=0.500).

Conclusion

Although women with uterine confined leiomyosarcoma experience high recurrence rates and poor survival outcomes, adjuvant treatment does not appear to confer a survival benefit.

2-Octylcyanoacrylate for the prevention of anastomotic leak

BACKGROUND

Anastomotic leak after colorectal surgery is a significant cause of morbidity and mortality. The aim of this study was to evaluate the impact of a reinforced colo-colonic anastomosis with tissue adhesive, 2-octylcyanoacrylate (2-OCA), on the integrity of anastomotic healing as measured by anastomotic bursting pressure.

METHODS

Sixty-eight female Sprague-Dawley rats underwent a rectosigmoid colon transection and a sutured end-to-end anastomosis followed by randomization to receive no further intervention or reinforcement with the tissue adhesive, 2-OCA. After seven postoperative days, a macroscopic assessment of the anastomosis, mechanical assessment to determine anastomotic bursting pressure, and a detailed semi-quantitative histopathologic healing assessment were performed.

RESULTS

Thirty-four animals were randomized to each group. Study characteristics did not differ between the groups. There was also no difference in the degree of adhesions present postoperatively. Although there was no difference between the net proximal and distal luminal areas in the two groups (0.37 cm²versus 0.55 cm², P = 0.26), the 2-OCA group exhibited evidence of stricture in 15% of anastomoses as compared with 3% in the suture-only group (P < 0.0001). Histologically, the presence of only fibroblasts density was statistically more evident in the 2-OCA group compared with the sutured-only anastomosis (P = 0.0183). There was not a significant increase in mechanical strength in the 2-OCA group (238.9 mm Hg) versus in the suture-only group (231.8 mm Hg). There was no difference in the rate of anastomotic leak in the 2-OCA as compared with the suture-only group (9.1 versus 8.8%).

CONCLUSIONS

Application of 2-OCA to reinforce a colo-colonic anastomosis clinically provides no benefit to its mechanical strength and detrimentally increases the rate of obstruction and/or stricture in this in vivo model.

Is it equivalent? Evaluation of the clinical activity of single agent Lipodox® compared to single agent Doxil® in ovarian cancer treatment

Background

In response to the critical shortage of liposomal doxorubicin (Doxil®) in the United States, the Food and Drug Administration (FDA) approved temporary importation of doxorubicin hydrochloride liposome (Lipodox®). The objective was to compare toxicity and clinical activity of Lipodox® with Doxil®.

Methods

Recurrent ovarian cancer patients who received Lipodox® were compared 3:1 to matched control Doxil® patients who had received Doxil®. Patients were matched based on age, stage, dose, platinum sensitivity, and prior treatments from an existing de-identified database. Patients receiving combination regimens were excluded.

Results

The data from 40 Lipodox® patients was compared to 120 matched control Doxil® patients. In this study, 17 (42.5%) of the Lipodox® patients were switched to Doxil®. The overall response rate Lipodox® was 4.3% (1/23) compared to 18% (20/111) in matched control Doxil® patients. In the platinum-sensitive patients, 100% progressed in the Lipodox® group compared to 78.4% in matched control Doxil® patients. The mean time to progression was 4.1 ± 2.8 months for Lipodox® and 6.2 ± 7.2 months in control Doxil®s ( p = 0·25). Toxicity was similar in the Lipodox® group and control Doxil® group.

Conclusion

Lipodox® for treatment of recurrent ovarian cancer did not appear to have equivalent efficacy compared to Doxil®. A prospective clinical study is warranted before Lipodox® can be deemed equivalent substitution for Doxil®.

Stercoral Perforation of the Colon during Pregnancy: A Case Report and Review of the Literature

Stercoral perforation of the colon, though rare, is associated with high mortality. Review of the literature identified only three prior cases reported during pregnancy. We report a case on a multiparous female presenting at 31 weeks of gestation with acute abdominal pain. Computed tomography suggested a sigmoid colon perforation. An urgent exploratory laparotomy was performed where feculent peritonitis and a stercoral perforation of the sigmoid colon was confirmed. A cesarean delivery and sigmoid colectomy with descending end colostomy was performed. While the newborn had an uncomplicated course, the mother developed an intra-abdominal abscess requiring operative management.

Clinically significant endometrial cancer risk following a diagnosis of complex atypical hyperplasia

OBJECTIVES

Because of the frequent detection of carcinoma in surgical specimens after hysterectomy for endometrial complex atypical hyperplasia (CAH), it has been suggested that patients with a preoperative diagnosis of CAH be referred to gynecologic oncology for potential lymphadenectomy. However, the risk of lymph node metastasis in such patients is unknown. We sought to determine the risk of endometrial cancer and to estimate the risk of lymphatic spread in women with a preoperative diagnosis of CAH.

STUDY DESIGN

We retrospectively reviewed the medical records of 150 consecutive patients with a preoperative diagnosis of CAH who subsequently underwent hysterectomy. Clinical characteristics and pathologic information were abstracted. Risk of lymphatic spread was modeled using previously published criteria and nomograms.

RESULTS

Fifty-five of the 150 patients (36.7%) had an incidental endometrial carcinoma at the time of hysterectomy. Among patients with a preoperative office biopsy compared to dilation and curettage, the rate of an incidental finding of cancer was 43.5% and 28.1%, respectively (p=0.054). Of patients with cancer, 1 (1.8%) had a grade 3 endometrial carcinoma, 4 (7.3%) had lymphovascular space involvement, and 6 (10.9%) had deep (>50%) myometrial invasion. For the 10 patients who underwent lymphadenectomy, one (10%) had lymph node metastases. Based on multiple models, the estimated risk of lymph node spread was 1.6%-2.1% for all women with a preoperative diagnosis of CAH and 4.4%-6.8% for the 55 women with endometrial cancer.

CONCLUSIONS

Given the high rates of underlying endometrial cancer and the potential need for lymphadenectomy, care for patients with a preoperative diagnosis of CAH desiring definitive management with hysterectomy should be referred to a gynecologic oncologist.

Risk of residual disease and invasive carcinoma in women treated for adenocarcinoma in situ of the cervix

OBJECTIVE

Cervical adenocarcinoma in situ (AIS) is increasing in incidence among reproductive-age women. Cervical conization is an alternative to hysterectomy that allows future fertility, however reports regarding the risk of residual AIS and underlying adenocarcinoma are conflicting. The purpose of this study was to determine the outcomes of a large cohort of women treated for AIS.

METHODS

The medical records of 180 women with cervical AIS evaluated at the University of Texas MD Anderson Cancer Center and its outlying clinics between 1983 and 2011 were reviewed for demographic information, treatment history, pathologic findings and outcomes.

RESULTS

The mean age at diagnosis was 33.8years (range 17.6-76.1years). 172 of the 180 women had at least one cone biopsy performed, with 110 (64.0%) undergoing a cold knife cone (CKC), and 62 (36.0%) undergoing a loop electrosurgical excision procedure (LEEP) as their initial method of treatment. Positive margins were noted in 35.0% of patients undergoing CKC compared with 55.6% undergoing LEEP (p=0.017). 71 patients ultimately underwent hysterectomy with residual disease noted in 10 patients (14.1%), 8 patients (11.3%) with residual AIS and 2 patients (2.8%) with invasive carcinoma. Of the 101 patients who did not undergo hysterectomy, 2 patients (2.0%) developed recurrent AIS at a median of 27.5months (range 18-37months) from the last cone, and none developed invasive carcinoma.

CONCLUSION

Patients undergoing conservative management for AIS with cervical conization alone should be monitored closely and counseled regarding the potential risks of residual and recurrent disease, even when negative cone margins are obtained.

Metastatic adenocarcinoma found in inguinal, pelvic and para-aortic lymph nodes 14 years following hysterectomy for adenocarcinoma in situ of the cervix

► Recurrent invasive adenocarcinoma after definitive therapy for AIS is a rare occurrence. ► Because of its unpredictable nature, AIS requires long-term and close surveillance.
