[Diagnosis and treatment of anorectal malignant melanoma--a report of 22 cases with literature review].

BACKGROUND & OBJECTIVE: Anorectal malignant melanoma (AMM) is an aggressive malignant tumor, and its treatment still remains controversial. This study was to summarize our experience on diagnosis and treatment of AMM. METHODS: Clinicopathologic records, including clinical feature, diagnosis, operation patterns, and prognosis, of 22 patients with AMM, treated in Jiangsu Provincial Cancer Hospital from 1977 to 2003, were analyzed retrospectively with literature review. RESULTS: The 22 patients with AMM accounted for 0.04% of all the patients diagnosed as malignant tumors of large bowel simultaneously in our hospital. Of the 22 patients, 6 were men, and 16 were women, with the median age of 61 (ranged 37-72). The most common complaints of AMM patients were hematochezia (86%), anus pain or discomfort (59%), local mass (27%), and so on. The misdiagnosis rate was 86%. The definite pathologic diagnosis rate before surgery was 48%. Of the 22 patients, 6 had distant metastasis; 11 underwent abdominoperineal resection, 5 underwent wide local excision (2 underwent salvage abdominoperineal resection who suffered from local recurrence after wide local excision), 2 underwent Parkos procedure, 1 underwent Hartmannos procedure, and 3 underwent sigmoid colostomy. The 1-, 3-, and 5-year survival rates of the 22 patients were 45.4%, 18.1%, and 9.1%, respectively. The median survival time was 12 months (95% confidence interval: 6-18 months). CONCLUSIONS: AMM is a rare disease with poor prognosis. It tends to be misdiagnosed. Abdominoperineal resection may be considered as the first choice for the AMM patients without distant metastasis.

The utility of squamous cell carcinoma antigen for the follow-up of patients with squamous cell carcinoma of the anal canal.

BACKGROUND: Thirty-three patients with histologic documentation of squamous cell carcinoma (SCC) of the anal canal underwent prospective serial collection of 234 serum samples for radioimmunoassay of SCC tumor-associated antigen. METHODS: There were 23 female and 10 male patients, with a median age of 55 years. Twenty-two of the 33 patients had multimodality therapy with radiation therapy and chemotherapy as initial treatment. RESULTS: The median follow-up was 22 months (range, 4-52 months), with a median of 13 serum specimens per patient (range, 1-23 specimens). Twenty-eight patients currently have no evidence of disease, 4 patients are alive with disease, and 1 patient died with disease. CONCLUSION: In these 33 patients, the sensitivity of the SCC tumor-associated antigen was 76%, specificity 86%, and positive predictive value 62%.

AIDS-associated malignancies.

Although currently diagnosed in about 40% of HIV-infected individuals at some point in their clinical course, AIDS-associated malignancies may increase in frequency as survival is prolonged and, particularly, as greater numbers of HIV infections occur in women. Although this review has been devoted to AIDS-defining cancers, there are suggestions from epidemiological studies that some of the more common cancers in the general population are beginning to be diagnosed at increased rates in HIV-infected people [141]. In addition, as children born with HIV infection show longer survival, increased cancer rates may be seen in this group as well. While recent advances have been made in understanding the pathogenesis of AIDS-associated malignancies, particularly KS, and modest therapeutic advances have been made, optimal therapy has yet to be defined for any of these neoplasms.

Combined surgery and chemoradiation as a treatment for the Buschke-Löwenstein tumour.

BACKGROUND: The Buschke-Löwenstein tumour (BLT) or giant condyloma acuminata is a rare disease which affects the anogenital region. Although histologically benign, it behaves in a malignant fashion, infiltrating the surrounding tissues. The morbidity and mortality from this tumour is high, as is the risk of recurrence following treatment. It lies on the continuum between the benign condylomata acuminata and squamous cell carcinoma. The human papillomavirus is implicated in its aetiology. Treatment is controversial, with topical chemotherapy, radiotherapy, immunotherapy and radical surgery all having been employed. Chemoradiation remains the mainstay of treatment for anal cancers but has not been routinely employed in the management of the BLT without squamous cell carcinoma transformation. METHODS: Two cases of extensive perineal BLT treated with chemoradiation and subsequent surgical excision are presented. RESULTS: The first patient had a good symptomatic response to the chemoradiation but unfortunately died of recurrent disease following surgery. The second patient had a macroscopically complete response to chemoradiation and remains well following abdominoperineal excision. CONCLUSION: Pre-operative chemoradiation has proved to be useful in management for histologically proven benign BLT

Chemotherapeutic options in the management of anal cancer.

During the past two decades, anal cancer has served as a paradigm for the successful application of chemoradiation to solid tumours; so far, it remains one of the few carcinomas of the gastrointestinal tract which are curable without the need for definitive surgery. Since the original contribution by Nigro in 1974, surprisingly few changes have been made to the standard of care in chemotherapy, which still consists of a combination of 5-fluorouracil and mitomycin C. However, many issues have yet to be clarified, such as the potential role of cisplatin as a substitute to mitomycin, as well as treatment-induced toxicity in HIV-positive patients. In this paper, the management of patients with anal cancer is presented, and new chemotherapeutic options are critically reviewed. Finally, the authors' opinion regarding currently unresolved issues in the treatment of these rare neoplasms is expressed.

Stromal neoplasms of the rectum and anal canal.

Nineteen mural-based stromal tumors of the rectum and anal canal were reviewed, with the objective of delineating pathologic features discriminative of malignancy in these uncommon neoplasms. Ten locally excised tumors failed to recur during long-term follow-up and were considered benign. All occurred in the submucosa and ranged in size from 1.0 to 7.0 cm (mean, 2.1 cm). Three were sparsely cellular; seven had the appearance of gastric-type cellular leiomyomas. All lacked nuclear atypia and displayed mitotic activity not exceeding 1 mitosis/50 high-power microscopic fields. In contrast, of nine tumors exhibiting malignant behavior, eight (89%) were located in the muscularis propria. Their mean size was 4.5 cm (range, 1.6 to 11 cm). Necrosis was present in six tumors (67%). Seven sarcomas retained a cellular leiomyomatous appearance but exhibited moderate cytologic atypia. Mitotic counts ranged from 5 to 58 mitoses/50 high-power microscopic fields. Three locally excised sarcomas recurred in the rectum at 2, 2, and 7 years. In five patients tumor recurred in the pelvis. Five patients died of disease 0.67, 1.2, 3, 5, and 11 years post-diagnosis. One patient died with sarcoma at 31 years. Three patients are without evidence of recurrent neoplasm 5, 5, and 7 years postresection. Our data indicate that not all anorectal, mural-based stromal neoplasms are a priori malignant. While location within the muscularis propria, size, nuclear atypia, and tumoral necrosis correlate with malignancy, mitotic activity is the cardinal indicator of sarcomatous behavior in stromal neoplasms of the rectum and anal canal.

Granular cell tumour (myoblastoma): two cases and a review of the literature.

Granular cell tumour is a rare neoplasm consisting of nests or ribbons of polyhedral cells with granular eosinophilic cytoplasm and small, dense nuclei. It may occur at various sites throughout the body. Two cases, one of the tongue and one of the rectum, are reported and the pathology and management of this uncommon neoplasm are discussed.
