Basal cell carcinomas (BCCs) are very frequent cutaneous cancers, often located on the face. Cure rates with surgery and radiotherapy are high, but these treatments have never been compared prospectively. A randomized trial was initiated in 1982 to compare surgery and radiotherapy in the treatment of primary BCC of the face measuring less than 4 cm. The primary end point was the failure rate (persistent or recurrent disease) after 4 years of follow-up. The secondary end point was the cosmetic results assessed by the patient, the dermatologist and three persons not involved in the trial. In the course of the trial, 347 patients were treated. Of the 174 patients in the surgery group, 71% had local anaesthesia and 91% frozen section examination. Of the 173 patients in the radiotherapy group, 55% were treated with interstitial brachytherapy, 33% with contactherapy and 12% with conventional radiotherapy. The 4-year actuarial failure rate (95% CI) was 0.7% (0.1-3.9%) in the surgery group compared with 7.5% (4.2-13.1%) in the radiotherapy group (log-rank P = 0.003). The cosmetic results assessed by four of the five judges were significantly better after surgery than after radiotherapy. Eighty-seven per cent of the surgery-treated patients and 69% of the radiation-treated patients considered the cosmetic result as good (P < 0.01). Thus, in the treatment of BCC of the face of less than 4 cm in diameter, surgery should be preferred to radiotherapy.
We report our institutional experience with the accuracy and usefulness of cervical amputations with frozen section evaluation of the endocervical margin in the management of preinvasive squamous epithelial lesions. Four hundred and fourteen consecutive patients, who underwent amputation of the cervix because of a preinvasive epithelial lesion, or discrepancy between cytologic and biopsy findings especially when colposcopic evaluation was unsatisfactory, had frozen section evaluation of the endocervical margin. Medical records were reviewed and pathologic findings were compared with those obtained on paraffin embedded sections. Frozen section analysis of the upper endocervical margin led to the diagnosis of a residual lesion in 90 (21.7%) cases. In 59 (14.2%) of these eases a further excision was performed during the same operative procedure leading to complete resection in 34 (8.2%) cases. In 403 (97.3%) cases the diagnosis based on the frozen section was corroborated by the permanent sections. For the diagnosis of insufficient cervical resection, the sensitivity and specificity of frozen sections were 93.8% and 99.7% respectively. We conclude that frozen section evaluation of the upper endocervical margin at the lime of cervical amputation is a reliable procedure that increases the rate of complete resection. The risks associated with additional anesthesia are then reduced, as are inconvenience to the patients and costs.
Melanoma in children is rare. Nevertheless, it is imperative that clinicians be aware that melanoma does occur in childhood. Yet there is very little information available on the clinico-pathologic variations, and the prognostic parameters of melanoma in children. This report presents the results of a multicenter study of 102 lesions originally diagnosed as cutaneous melanoma, conducted among 5 Western European countries and collected during the period 1961-1994. Criteria for inclusion in the study included: (1) diagnosis of cutaneous melanoma; (2) age up to 16 years at diagnosis; and (3) availability of representative microscopic slides. On the basis of the histologic review only, 60 lesions were confirmed as melanoma, and 42 lesions initially diagnosed as melanoma were reclassified as nevi; 31 of the latter contained a predominance of spindle cells. The only significant parameter associated with the development of metatases or fatal outcome was thickness of more than 2.00 mm. The 5-year survival rate observed in this study was 84%. Based on these findings we conclude that considerable over-diagnosis of melanomas in children occurs. In order, therefore, to give consistent epidemiological data on melanomas in children and to improve proper recognition of their diagnostic features, both by clinicians and by pathologists, we propose to set up a central registry of melanomas in children in Europe, under the auspices of the European Organization for Research and Treatment of Cancer.
Between January 1956 and December 1990, 17 patients younger than 17 years with available pathological screens of de novo cutaneous melanoma, and with no other risk factors (xeroderma pigmentosum, giant congenital naevi, congenital melanoma or a proven family history of dysplastic naevus syndrome) were seen at the Gustave-Roussy Institute. The median age was 9 years and 9 months (range 2 years and 3 months-16 years and 9 months). The primary disease was located in the lower extremities in 10 cases, the trunk in five cases, and the upper extremities or head and neck in one case. The disease was localized for 10 patients at presentation (stage I), six had proven nodal metastasis (stage II) and one patient had nodal and breast metastases. The median thickness of the primary lesion was 2.89 mm (range 0.64-10). Five tumours were at level III on Clark's index, eight at level IV and four at level V. Six cases were classified as superficial spreading, two as unclassified radial growth, three nodular, three with Spitzoid cells, and three were unclassified. Two patients presented local recurrence with an initial unclassified melanoma, with a thickness greater than 2.5 mm. At a median follow-up time of 7 years, two patients had died from recurrent disease, and one patient had died from a second malignancy.
This report describes two cases of malignant serous cancers with areas of borderline malignancy, which appear to have arisen within benign glandular inclusions of coelomic origin in pelvic or para-aortic lymph nodes. The patients were 44 and 62 years of age. In both cases the nodes contained benign glandular inclusions lined by a single layer of epithelium which resembled that of tubal epithelium. The location of the glandular epithelium varied from within the fat near the node to intracapsular, subcapsular, or interfollicular positions. The number of glands ranged from few to extensive. In both cases the glandular inclusions disclosed epithelial proliferations, ranging from minor degrees of stratification with formation of small papillae of atypical cells (borderline serous tumor) to almost solid tumor typical of serous cancer. In both cases, the borderline and cancerous tumors exhibited areas of transition which appeared to arise from benign glands. Although benign glandular inclusions of coelomic origin are well documented to occur in pelvic or para-aortic lymph nodes of 5-20% of women and have been considered to be of significance only because of the possibility of the misdiagnosis of cancer, it should now be recognized that the glandular inclusion cysts themselves can become neoplastic.
BACKGROUND AND DESIGN:Five percent to 10% of cutaneous malignant melanomas (CMMs) occur in a familial setting. Clinical, epidemiologic, and genetic studies of familial CMM in different regions of the world have led to various results. To assess the characteristics of familial CMM in France, the clinical, histologic, and epidemiologic characteristics of 295 patients with CMM were recorded, and a comprehensive familial investigation was performed for each case. Patients with a family history of CMM were compared with nonfamilial cases.RESULTS:Cutaneous malignant melanoma occurred as a familial cancer in 22 (8%) of 295 patients. Among the multiple variables studied, those significantly associated with the familial occurrence of CMM were red hair, inability to tan, and presence of clinically atypical moles. When these variables were considered together in a multivariate analysis, only the association with red hair (P = .001) and atypical moles (P < .05) remained significant. In addition, the patients with familial melanoma exhibited the following tendencies: a younger age at diagnosis, a higher number of moles, and the development of multiple primary melanomas, but these results did not reach statistical significance. Factors relating to UV light exposure, histologic features of CMM, course of the disease, and occurrence of nonmelanoma cancers showed a similar distribution between familial and nonfamilial cases.CONCLUSION:A familial investigation should be performed for each patient with CMM in France, particularly when he or she exhibits phenotypic risk factors for CMM such as red hair and atypical moles.
To determine whether neural invasion or other clinico-pathological factors are prognostic, we performed a retrospective study on 339 rectal carcinomas. The overall 5-year survival was 62%. In the multivariate analysis, age over 60 years, a distance from the anal verge of less than 6 cm, the number of positive lymph nodes, neural invasion and tumour penetration were found to be prognostic. A scoring system identified five prognostic groups of patients. Neural invasion is an independent prognostic factor in our scoring system and it is suggested that this parameter should be taken into consideration for postsurgical treatment.
Two cases of colonic carcinomas with multidirectional differentiation are presented. Both tumors showed light microscopic and immunohistochemical evidence of areas of adenocarcinomatous, squamous cell carcinomatous, and neuroendocrine differentiation. Only six similar cases have been previously reported. These highly malignant tumors support the recent concept of a multipotential stem cell within the mucosa of the gastrointestinal tract capable of differentiation in several directions.
Uterine cervix carcinoma is considered by some authors to carry a poor prognosis in young patients (< 35 years of age). From 10 years, many series have been published with divergent conclusions. However, a group of patients with poor prognosis could be individualized ; age < 30 years, locally agressive tumour, poorly differentiated, nodal involvement, amplification of c-Myc proto-oncogene. New imaging technics and coelioscopy could help to the diagnosis. The role of combined treatment remains to be demonstrated and biological factors (kinetics. oxygenation) will help in the future to more adapted treatments.
This phase III randomised trial examined the early effects of two low dose rates (0.38 and 0.73 Gy/h) in brachytherapy of stage I and IIp cervical cancer patients. A total of 204 patients were included between January 1985 and September 1988. Since the main analysis of this paper concerned surgical difficulties, only the 155 patients (76%) on whom surgery was performed at the Institut Gustave-Roussy were retained in this analysis. Treatment consisted of uterovaginal 137Cs irradiation followed by immediate or deferred surgery. The two groups were similar for pretreatment characteristics except for endocervix involvement. Their brachytherapy parameters were also similar (60 Gy pear dimensions, doses to critical organs, total kerma, etc.). The factors with a poor prognosis were, for surgical difficulties, older age, stage II and a small irradiated pear volume; for difficulties with haemostasis, immediate surgery, stage II and previous surgery; and for difficulties in dissection, lymph node involvement. The dose rate significantly influenced surgical difficulties for the stage IIp patients operated on by deferred surgery. Those treated with the higher dose rate showed a 2-fold increase in surgical difficulties compared to those irradiated at the lower dose rate (P = 0.03). The independent prognostic factors for sterilisation of the surgical specimen were small tumour size and absence of lymph node involvement. An inverse dose rate effect was observed for medium size tumours, with significantly more sterilisations observed in stage IIp patients in the lower dose rate group (P < 0.01).
The intra-cellular uptake of the weakly basic radiosensitiser pimonidazole (PIMO) was determined as a function of the pigmentation of Na11+human melanotic melanoma cells in vitro. Two experimental conditions were considered: exponentially growing cells (Exp.) and plateau-phase cells (PI). The melanin content of Na11+cells ranged from 500 μg/g cell weight in exponentially growing cells to 6000 μg/g in heavily pigmented plateauphase cells. Cells were exposed to PIMO (medium dose, 0.2 mmol/dm3; 58.2 μg/ml). The intra-cellular concentration ranged from 163 μg/g in Exp. to 900 μg/g in pigmented Pl.; the latter being equivalent to an intra-to extracellular concentration ratio (Ci/Ce) of 17. However, this increase in the cellular uptake of PIMO was not accompanied by an increase in radiosensitising efficiency. In comparison, the Ci/Ce for etanidazole (ETA), a radiosensitiser that is uncharged at physiological pH, remained approximately constant at 1 for all values of melanin contents. Treatment of Na11+tumours in vivo with [3H]-PIMO resulted in a tumour: blood ratio of about 3 at 30–60 min after administration. However, at 24 h a grain count of label derived from [3H]-PIMO showed that picnotic areas of tumours contained levels that were some 40 times greater than the background value. This high level of label was coincident with areas of highest apparent melanin content. In conclusion, PIMO accumulates in very heavily pigmented melanoma cells present in necrotic zones with picnosis. As these cells are probably non-clonogenic, PIMO is not suitable for use in melanoma radiotherapy.
