Mycobacterial Cell Wall

Squamous cell carcinoma (SCC) is a common dermatological neoplasia found in large animal species. Treatment options, such as surgery and cryotherapy may be difficult or not feasible. Alternative therapies, such as immunomodulating drugs, can potentially be used for companion large animals. The hypothesis of the following retrospective study is: following multiple intravenous and intralesional injections of a mycobacterial cell wall stimulant (MCW) regression of SCC in equine, bovine and caprine patients will be observed. In this observational-retrospective case series, patients included are 2 bovine, 2 caprine and 3 equine patients. The medical records at two different teaching veterinary hospitals were searched for cases with a positive histopathological diagnosis of squamous cell carcinoma that were subsequently treated with MCW, as either the sole therapy, or in conjunction with other therapies. Seven cases were included in this retrospective study. The median duration of therapy was 56.5 days, with 3 of the 7 patients being euthanized. Significant complications were seen in 3/7 patients. Repeated injections of a MCW may lead to reduction in lesion size of SCC in some cases, but long-term resolution is unlikely and the risk of significant complications is high; due to limited sample size and the variety in species, it is difficult to conclude if MCW is an effective therapy for SCC.

BACKGROUND: Penis cancer worldwide has an incidence of 0.51- 8.3 per 100 000 males. It is treatment can be surgical, conservative or radical, with adjuvant treatment radiotherapy and chemotherapy. The objectives were: to determine histologically the most common type of penile cancer, the place of involvement, and the most used surgical treatment. METHODS: It is a descriptive, retrospective study realized in Dr. Juan Tanca Marengo National Oncological Institute, between the periods of January 2010 to December 2015. Patients with a histopathological diagnosis of penile cancer were included; the variables studied were age, location, presence of lymph nodes, histopathology, recurrence, metastasis and surgery performed; the mean and standard deviation were obtained. For the statistical analysis Excel 2016 and SPSS were used. RESULTS: The patients studied were 58 with penile cancer; it was evidenced, in relation to age, an average of 59 years and standard deviation was obtained +/- 14.74. The lesion was located more frequently in the glans 41 %, followed by a total involvement of the penis with 38 %; in the case of the nodes they were palpable in 24 patients. The most frequent histological type was squamous cell carcinoma 67 %. The most used treatment was subtotal penectomy in 62 %. CONCLUSIONS: It was determined that squamous cell carcinoma was the most prevalent histological type, being located mainly in the glans; the technique most used was subtotal penectomy. It is recommended to pay attention early when there is evidence of a lesion at the level of the penis, the early treatment of these lesions improves the patient's prognosis.

BackgroundConjunctival melanoma is the second most common conjunctival malignant tumour after squamous cell carcinoma, usually arising from primary acquired melanosis and less commonly from a conjunctival naevus or de novo. We report four cases of conjunctival melanoma masquerading as ocular surface squamous neoplasia.MethodsFour patients (2 females and 2 males; mean age 60.7 years; range 41–72 years) were referred for suspicious conjunctival lesions. In all cases, the lesions had a perilimbal location, were non-pigmented (cases 1 and 3) or mildly pigmented (cases 2 and 4), had a fleshy (cases 1, 2 and 4) or papillomatous (case 3) appearance and involved the corneal surface. In each case, our main clinical differential diagnosis included conjunctival intraepithelial neoplasia and squamous cell carcinoma. All four patients underwent an excisional biopsy with double freeze-thaw cryotherapy and alcohol keratoepitheliectomy.ResultsIn all four cases, the histopathological diagnosis was of invasive conjunctival melanoma with extension to the deep surgical margins. Adjuvant therapy consisting of strontium-90 β radiotherapy (all 4 patients) and topical Mitomicyn C (patient 2) was administered.ConclusionConjunctival melanoma can clinically resemble ocular surface squamous neoplasia. Clinical impressions therefore need to be confirmed histopathologically.

Local Chemotherapy

Background: Squamous cell carcinoma (SCC) is one of the most common cancers involving skin and oral mucosa. Although this condition’s gold-standard treatment is the surgical removal of the lesions, the physician must propose alternative treatments in some cases due to the patient’s ineligibility for surgery. Among the available alternative therapies, local chemotherapy may represent an initial treatment in combination with radiotherapy or systemic chemotherapy due to the low frequency of side-effects and the lack of necessity for expensive devices. Methods: In this paper, we review all available literature in various databases (PubMed, Scopus-Embase, Web of Science), proposing local chemotherapy as a treatment for cutaneous and oral SCC. Exclusion criteria included ocular lesions (where topical treatments are common), non-English language, and non-human studies. Results: We included 14 studies in this review. The majority were case reports and case series describing the treatment of non-resectable localized SCC with either imiquimod or 5-fluorouracil. We also analyzed small studies proposing combination treatments. Almost all studies reported an excellent clinical outcome, with a low risk of relapses in time. Conclusions: Resection of the lesion remains the gold-standard treatment for SCC. When this approach is not feasible, local chemotherapy may represent a treatment alternative, and it may also be associated with radiotherapy or systemic chemotherapy.

AbstractVaginal and vulvar squamous cell carcinoma (SCC) are rare tumors that can be challenging to treat in the recurrent or metastatic setting. We present a case series of patients with vaginal or vulvar SCC who were treated with single-agent pembrolizumab as part of a phase II basket clinical trial to evaluate efficacy and safety. Two cases of recurrent and metastatic vaginal SCC, with multiple prior lines of systemic chemotherapy and radiation, received pembrolizumab. One patient had significant reduction (81%) in target tumor lesions prior to treatment discontinuation at cycle 10 following confirmed progression of disease with new metastatic lesions (stable disease by irRECIST criteria). In contrast, the other patient with vaginal SCC discontinued treatment after cycle 3 due to disease progression. Both patients had PD-L1 positive vaginal tumors and tolerated treatment well. One case of recurrent vulvar SCC with multiple surgical resections and prior progression on systemic carboplatin had a 30% reduction in her target tumor lesions following pembrolizumab treatment with a PD-L1 positive tumor. Treatment was discontinued for grade 3 mucositis after cycle 5. Pembrolizumab may provide some clinical benefit to some patients with vaginal or vulvar SCC and is overall safe to utilize in this population. Future studies are needed to evaluate the efficacy of pembrolizumab in these rare tumor types and to identify predictive biomarkers of response.
