Combination Trimodality Therapy Using Vismodegib for Basal Cell Carcinoma of the Face.

ABSTRACT: Background. For large basal cell carcinomas (BCCs) of the head and neck, definitive surgery often requires extensive resection and reconstruction that may result in prolonged recovery and limited cosmesis. Vismodegib, a small-molecule inhibitor of the hedgehog pathway, is approved for advanced and metastatic BCCs. We present a case of advanced BCC treated with combination of vismodegib, radiotherapy, and local excision resulting in excellent response and cosmesis. Case Presentation. A 64-year-old gentleman presented with a 5-year history of a 7?cm enlarging right cheek mass, with extensive vascularization, central ulceration, and skin, soft tissue, and buccal mucosa involvement. Biopsy revealed BCC, nodular type. Up-front surgical option involved a large resection and reconstruction. After multidisciplinary discussion, we recommended and he opted for combined modality of vismodegib, radiotherapy, and local excision. The patient tolerated vismodegib well and his right cheek lesion decreased significantly in size. He was then treated with radiotherapy followed by local excision that revealed only focal residual BCC. Currently, he is without evidence of disease and has excellent cosmesis. Conclusions. We report a case of locally advanced BCC treated with trimodality therapy with vismodegib, radiotherapy, and local excision, resulting in excellent outcome and facial cosmesis, without requiring extensive resection or reconstructive surgery.

Project description:BackgroundSurgery is the primary treatment for basal cell carcinoma (BCC). In locally advanced basal cell carcinoma (laBCC), surgery may cause functional or aesthetic damage. In laBCC, neoadjuvant administration of vismodegib, an inhibitor of the Hedgehog signaling pathway, may reduce tumor size, facilitate resection, and reduce functional and aesthetic consequences of surgery. The VISMONEO study assessed efficacy and safety of vismodegib in neoadjuvant treatment of laBCC.MethodsVISMONEO (NCT02667574) is an open-label, noncomparative, multicenter, phase 2 study. Patients with ≥1 histologically confirmed facial BCC, inoperable or operable with functional or major aesthetic sequelae risk, were included. Oral vismodegib 150 mg was administered once daily for 4 to 10 months before planned surgery, which was performed once the best response under vismodegib was observed. Primary endpoint was percentage of patients with BCC with tumor downstaging following surgical resection after neoadjuvant vismodegib. Downstaging was defined according to a 6-stage surgical classification related to the aesthetic and functional consequences of surgery.Findings55 patients (median age: 73 years) with laBCC were included from November 2014 to June 2015. At inclusion, 4 patients were inoperable, 15 were operable with a major functional risk, and 36 were operable with a minor functional risk or a major aesthetic risk. Mean size of target lesion was 47.3 mm (SD: 27.2 mm). 44 patients presented with downstaging after vismodegib treatment (80%; 95% confidence interval [CI], 67 to 90). Of these 44 patients, 27 had a complete response (25 proved by biopsy). Mean treatment duration was 6.0 months. Overall Response Rate according to RECIST 1.1 criteria was 71% (95% CI, 59 to 88). At 3-years of follow-up, 16/44 patients had known recurrence (36%; 95%CI, 22 to 51).InterpretationNeoadjuvant vismodegib allows for a downstaging of the surgical procedure for laBCCs in functionally sensitive locations.FundingVISMONEO was funded by F. Hoffmann-La Roche Ltd.

Project description:INTRODUCTION:Locally advanced basal cell carcinoma (laBCC) has always represented an uncommon, difficult-to-treat form of skin cancer, but approval of the Hedgehog inhibitor (HHI) vismodegib has provided an effective, well-tolerated therapy. While this drug has been shown to be a safe and effective during treatment, to date the effect of its prolonged use at a low dose after complete remission (CR) of laBCC has not been described. The aim of this study was to report our experience regarding the long-term efficacy of low-dose vismodegib as maintenance therapy in patients with CR of the disease during a 1-year follow-up period. METHODS:An observational retrospective study was conducted at the Non-Melanoma Skin Cancer Unit of the University of Federico II (Naples). Patients who reported complete regression of their advanced BCC after vismodegib treatment were included in the study and subsequently separated into two groups. One group of patients continued with the "drug holiday" regimen consisting of a once-weekly maintenance dosage of 150 mg vismodegib for 1 year after CR of their BCC; the second group comprised patients who decided not to take a maintenance dosage following complete regression of their BCC. RESULTS:A total of 42 patients (35 males, 7 females) with a median age of 75.2 years and complete regression of their advanced BCC after treatment with vismodegib were included in the study. Of these, 27 (64%) patients continued with the "drug holiday" regimen, receiving a once-weekly maintenance dosage of 150 mg vismodegib for 1 year after CR of their BCC, and 15 (36%) patients decided not to take the maintenance dosage. Patients who continued to receive the low-dose vismodegib treatment did not present any BCC recurrence during 1-year follow-up period, while those who discontinued vismodegib treatment reported a BCC recurrence rate of 26.6% (4/15 patients) during the 1-year follow-up period. CONCLUSIONS:Our retrospective analysis focused on the use of a novel therapeutic scheme based on prolonged use of vismodegib after CR of the laBCC. The results demonstrate that the maintenance dose of vismodegib described herein effectively eliminated skin tumor recurrence and reduced the severity of common adverse events, thus increasing patient compliance.

Project description:ImportanceThe outcomes of vismodegib treatment in a relatively large cohort of study participants with periocular locally advanced basal cell carcinoma (POLA-BCC) may guide physicians when considering this treatment.ObjectiveTo report the outcomes of vismodegib treatment in patients with POLA-BCC in the Safety Events in Vismodegib (STEVIE) study.Design, setting, and participantsThis post hoc subgroup analysis from the STEVIE single-arm, multicenter, open-label cohort study screened all 1215 participants for ocular or periocular involvement and identified 244 participants with POLA-BCC or metastatic BCC. Data for the first STEVIE trial were collected from 167 treatment locations in 36 countries from June 30, 2011, to June 14, 2017. This post hoc analysis was performed from April 1 to August 31, 2019.Main outcomes and measuresResponse to treatment and adverse events.ResultsOcular or periocular involvement was found in 244 of 1215 STEVIE participants (20.1%), who constituted the analytic sample. The median age of the study participants was 72.0 (interquartile range [IQR], 60.0-82.0]) years, and they included 143 men (58.6%). Locally advanced BCC was diagnosed in 238 of the 244 participants (97.5%) and metastatic BCC, in 6 (2.5%). The median duration of exposure to vismodegib was 40.0 (IQR, 20.0-78.0) weeks, specifically 39.7 (IQR, 19.9-76.0) weeks for POLA-BCC and 92.4 (IQR, 53.2-163.0) weeks for metastatic BCC. Sixty-nine participants (28.3%) sustained serious adverse events (alopecia, muscle spasms, dysgeusia, weight loss, decreased appetite, asthenia, ageusia, nausea, fatigue, and diarrhea). Two hundred thirty-two study participants (95.1%) sustained more than 1 adverse effect. The overall mean (SD) number of drug-related adverse effects per study participant by first adverse event, regardless of the severity, was 5.48 (3.84). Discontinuation of vismodegib treatment owing to an adverse event was recorded in 58 participants (23.8%). During the study, 22 participants (9.0%) died, 70 (28.7%) achieved complete response, and 94 (38.5%) achieved partial response.Conclusions and relevanceVismodegib was well tolerated by the study participants with POLA-BCC. The safety of vismodegib treatment according to the STEVIE trial findings is consistent with that reported in previous studies. These data may be helpful when considering vismodegib for patients with POLA-BCC.
