High-dose-rate interstitial brachytherapy of Bartholin's gland: A case report

Case series on the management and outcomes of Bartholin gland carcinoma

OBJECTIVE

To evaluate the management and outcomes of Bartholin gland cancer at a single tertiary institution.

STUDY DESIGN

A single institution retrospective review of 9 cases of BGC between 2004 and 2022 was conducted. Demographics, pathological characteristics, treatment, follow up and oncologic outcomes were extracted from clinical records. Data are summarised using descriptive statistics and survival probabilities are presented with Kaplan Meier graphs.

RESULTS

Ten cases of BGC were identified at our institution over a period of 18 years. Nine out of ten clinical records were available for analysis. Eight patients presented with vulval swelling and four were treated initially for Bartholin cyst or abscess. One patient had a histological diagnosis of adenoid cystic carcinoma while the remaining were squamous cell carcinomas. With the exception of stage I disease chemoradiation was the primary mode of treatment. Adverse events included skin desquamation (4/9), venous thrombo-embolism (2/9), gastro-intestinal (1/9) and neurotoxicity (1/9). Median follow up was 60 months with a 5-year recurrence free and overall survival at 76 % and 64 % respectively.

CONCLUSION

BGC may present after a long duration of symptoms and at advanced stages. Primary chemoradiation appears to be a feasible treatment option in advanced disease with the benefit of decreased morbidity.

A Case of Adenoid Cystic Carcinoma Mimicking a Bartholin Cyst and Literature Review

Adenoid cystic carcinoma of the Bartholin Gland (BG-ACC) is a rare form of vulval cancer with only approximately 350 reported cases since 1864. A review of available literature and case reports suggests an aggressive nature with protracted clinical symptoms and a tendency for local recurrence despite adequate surgical excision with or without adjuvant radiotherapy. Survival rates of 71% and 59% are reported at five and ten years. This case report endeavours to add to our body of knowledge regarding this rare disease and thus help broaden and improve our understanding of management and treatment success.

Bartholin gland cancer

INTRODUCTION

Bartholin gland carcinoma is an extremely rare condition. Because of its, phase III trials have not been carried out, there exists no unanimous consensus on treatment and guidelines are missing.

METHODS

All studies reporting cases of Bartholin cancer were collected and screened for the evaluations. Baseline characteristics of studies were extracted and were queried in a database.

RESULTS

A total number of 133 manuscripts collected were available for the review process, representing a total number of 275 reported cases. The histological type of Bartholin gland cancer was specified in 90.4% cases: 30.7% cases were squamous cell carcinoma, 29.6% adenoid cystic carcinoma, 25% adenocarcinomas. At multivariate analysis adenocarcinoma histotype and positive lymph node were statistical correlated with worse prognosis.

CONCLUSION

Bartholin gland cancer remains a challenge for gynecologic oncologists. To better understand and treat this disease, centralization to referral centers and design of multi institutional trials is crucial.

Management of Bartholin's gland carcinoma using high-dose-rate interstitial brachytherapy boost

PURPOSE

To describe the patterns of use, clinical outcomes, and dose-volume histogram parameters of high-dose-rate interstitial brachytherapy (HDR-ISBT) in the management of Bartholin's gland cancer.

METHODS AND MATERIALS

Five patients with Stage II-III Bartholin's gland carcinoma treated with CT-based HDR-ISBT boost were reviewed. Plans were generated using an inverse planning simulated annealing algorithm. Dose-volume histogram parameters were assessed. The total doses of HDR-ISBT and EBRT were converted to total equivalent dose in 2Gy (EQD2).

RESULTS

All 5 patients received HDR-ISBT as a boost (median dose, 30Gy) after EBRT (median dose, 45Gy). Three patients received postoperative irradiation for gross residual tumor or positive surgical margins and 2 patients were treated by primary chemoradiotherapy. The median V100, D90, and D100 for the CTV were 98.3%, 89Gy10, and 64Gy10 (EQD2), respectively. A complete response was observed in all patients. No local recurrence occurred. All patients remain alive and free of disease (median followup, 78 months; range, 8-93). Severe vaginal toxicities were observed, including vaginal necrosis that resolved with hyperbaric oxygen therapy.

CONCLUSIONS

HDR-ISBT boost after EBRT offers excellent long-term local control in patients with Bartholin's gland carcinoma. HDR-ISBT should be considered for positive surgical margins or residual tumor after surgery and for locally advanced malignancies treated by primary chemoradiotherapy.

Primary treatment of Bartholin's gland carcinoma with radiation and chemoradiation: a report on ten consecutive cases

We reviewed our experience with primary radiation therapy for Bartholin's gland carcinoma (BGC) as an alternative to traditional surgical treatment. A retrospective study reviewed records from the Cancer Data Registry and Research Patient Data Registry from 1986 to 2002. Charts of ten women identified with BGC were reviewed for demographic information, presenting symptoms, tumor characteristics, treatment modalities, and complications, as well as for recurrence and survival. The incidence of BGC was 2.13% of all invasive vulvar cancer cases at the Massachusetts General Hospital (MGH). Four patients presented with clinical stage I disease, one with stage II, three with stage III, and two with stage IV. The median age at diagnosis was 63.5 years. There were five squamous cell carcinomas, two adenoid cystic carcinomas, two mucinous adenocarcinomas, and one small-cell carcinoma. After a change in treatment policy in 1986 from primary surgery that had often required postoperative radiation therapy, ten consecutive patients were treated with primary radiotherapy or chemoradiation therapy. Treatment included teletherapy combined with a boost to the primary site, regional nodes and/or interstitial brachytherapy. Short-term complications were mild and well tolerated; one patient developed late radiation-associated pelvic fractures. Four tumors recurred with a mean time to recurrence of 31.2 months. The median follow-up was 87.2 months (45-142). Three- and 5-year survivals were 71.5% and 66%, comparable to outcomes after surgery and postoperative radiation therapy. We conclude that primary radiation or chemoradiation therapy offers an effective alternative to surgery in the treatment of BGC with preservation of genital function and low morbidity.
