The clinicopathologic findings of 13 patients having extramammary Paget's disease of the vulva are discussed with emphasis on its histogenesis and biological behavior. For the purpose of study and assessment of prognosis, these cases were divided into two groups, those with an underlying invasive cutaneous adnexal adenocarcinoma, and those lacking an underlying invasive lesion. Four cases contained invasive cutaneous adnexal adenocarcinoma; in one of these the invasion was superficial. Three of the cases with an invasive lesion and three other cases showed in situ adenocarcinoma of sweat glands. Surgical treatment is mandatory for both groups of patients. The prognosis was excellent for the patients having Paget's disease without an underlying invasive carcinoma. From the literature, the prognosis of those with an underlying invasive carcinoma of the vulva appears to be less favorable. Multiple surgical excisions may be required to control the recurrences and metastases. A frequent association with other internal malignancy was observed. In four cases, second malignancies were found. Of special interest was the demonstration in one case of columns of neoplastic cells extending from involved sweat glands to the surface epithelium via the intradermal sweat duct. Our study leads us to support the concept that the Paget's cells, in a number of cases, are derived from an underlying carcinoma in situ of sweat gland origin.

Two cases of carcinoma in situ of the male breast are described: in one patient it arose as a complication of gynecomastia; in the other, it occurred 'de novo' and proceeded to infiltration with widespread metastases. We reviewed 233 cases diagnosed clinically and histopathologically as gynecomastia to see if we could discover other instances of malignant transformation but none was found. Thirty-two cases of infiltrating male breast cancer were also examined. In 11 there was associated intraduct change. In only one of the 32 cases was there evidence of associated microscopic gynecomastia.

Tumor-specific immunity to carcinoma of the colon, pancreas and stomach was assayed by tube LAI. Cancers of the colon, pancreas and stomach, were shown to possess organ-type specific neoantigens. In 115 patients with colon cancer, 100%, 75%, 61% with Dukes' A, B and C cancer were LAI positive, respectively. Even a microfocus of in situ cancer in a colon adenoma was sufficient to stimulate measurable tumor-specific immunity in the host. In Dukes' D cancer, 25% of patients with widespread metastasis were positive, whereas 100% with solitary lesions were positive. Reactive leukocytes from patients with colon cancer did not react to extracts of normal bowel mucosa or villous adenoma from LAI-negative patients. Leukocytes from 19% (3 of 16) of patients with colon adenomas reacted to the extract of colon cancer but not normal colon mucosa. Moreover, the LAI-positive response of the patients with colon adenomas or colon cancer is directed to a colon cancer TSA which is linked to beta2-microglobulin. These studies suggest that some colon adenomas express TSA before morphological evidence of cancer. It is not known if the acquisition of a cell surface TSA is an irreversible step toward unrestrained growth and metastasis. In pancreatic cancer, 100% of patients with cancers less than 5 cm and without metastasis were LAI positive, whereas 29% were positive when the cancer was greater than 5 cm or had metastasized. In Patients with stomach cancer, 100% with Stage II and 46% with Stage III and IV cancer were LAI-positive. Leukocytes from patients with other GIT cancers and from patients with inflammatory bowel disease or pancreatitis did not react with extracts of colon, stomach or pancreatic cancer. Leukocytes from patients with metastatic cancer, usually did not react in the tube LAI assay because their surfaces were coated in vivo with TSA. LAI reactivity was present when CEA was not detectable and when CEA levels were elevated LAI activity was often absent. The present study suggests that the automated tube LAI shows sufficient promise to warrant studies to determine its efficacy for the diagnosis of GIT cancers.

True early forms of mammary cancer include tumours undetectable in routine clinical examinations and histologically presenting intraductal and lobular cancer (cancer in situ and with beginning invasion) in the absence of metastases. Parallel histological and cytological examinations and cytospectrophotometric determination of the DNA content increase the validity of the differential diagnosis between benign displasias and carcinoma in situ. Stages of composite clinico-roentgenilogical and morphological diagnosis of early mammary cancer have been developed. Two mammographic signs: accumulations of finest calcinates and filamentous tumour node less than 10 mm in diameter, permit to diagnose clinically latent cancer which has two forms of growth, diffuse and nodular. The diffuse form in some cases presents a stage preceeding the nodular form.

Carcinoma of the larynx is best managed in an interdisciplinary centre with wide therapeutic and rehabilitative services. Current management is confused, but may be simplified by consideration of three groups: 1) no fixation of laryngeal structures, 2) fixation of laryngeal structures and extension beyond the larynx, 3) all others including carcinoma in situ, verrucous carcinoma, transglottic tumor, and squamous carcinoma with marked airway obstruction. The rational treatment of Group 1 glottic tumors is primary radiation, which produces 75% crude and 92% corrected five year tumor free survival. If surgery is undertaken as primary treatment or for salvage, a vertical hemilaryngectomy may preserve the voice. Group 1 supraglottic carcinomas may be divided into supraglottic and marginal. Thirty per cent have palpable nodes at diagnosis and a further 20% occult disease in the cervical chain. Irradiation of neck nodes or block dissection is an integral part of treatment. The indications for a supraglottic horizontal partial laryngectomy are outlined. Where indicated this has five year survival figures of 70%. Recurrence is usually in the neck. Marginal tumors have a 50% five year survival rate when treated by conservation surgery combined with pre-operative radiation. Recent radiotherapeutic advances have improved treatment of these lesions. Thirty to 40% of patients with Group 2 tumors have regional metastases at presentation. There are no fixed protocols for treatment of these patients, less than 50% of whom will survive five years tumor free. The difficulty in carrying out a protocol based on pre-operative radiation with planned surgery is outlined. Under optimum conditions treatment should be primary radiation with salvage surgery for failures or recurrence, for the results are almost as good as primary surgery but 30% of larynges are saved. The difficulties of diagnosing recurrent tumor in irradiated tissue are discussed. Care must be taken to recognize that group of patients in whom tissue edema is the result of perichondritis rather than tumor recurrence, because in these patients surgery is extremely hazardous. Problems of diagnosis and methods of treatment of carcinoma in situ, and verrucous carcinoma are described. Transglottic carcinomas are defined and treatment is primary total laryngectomy with appropriate neck dissection. Similarly if tumors are causing major airway obstruction, treatment is by primary laryngectomy.

Three cases of primary nonpapillary carcinoma of the urinary bladder diagnosed by urinary cytology and multiple biopsies were reported. Bladder specimens of two of the patients were totally embedded for step-sections that were mapped after histopathologic study. Atypical hyperplasia and carcinoma in situ with foci of microscopic invasion affected the bladder mucosa and extended continuously to the distal ureters as well as prostatic urethra. Multicentric distribuion of the abnormal epithelium was definite in one case, and the bladder mucosa was extensively denuded in the other case. Metastasis to one of the regional lymph nodes was noted in the remaining one case. The origin of Pagetoid cells occurring in two of the cases is obscure, but we presume that these cells may represent transformed tumor cells showing differentiation toward the surface umbrella cells, or they are derived from Brunn's nests where the cells may gain potential to differentiate to glandular epithelium.

Pre-treatment data from tumour biopsies labelled in vitro with tritiated thymidine are reported for 54 patients undergoing radical radiotherapy by 137Cs or Cathetron 60Co intracavitary insertions plus external irradiation for carcinoma of the uterine cervix. Labelling indices were obtained ranging from 1.8 to 27.8%. No correlation was observed between mean labelling indices and the histological type of tumour or its degree of differentiation. Comparison of data obtained in this study with previously reported data for carcinoma in situ and invasive carcinoma indicate that with increasing clinical stage of the disease, a considerable lengthening of the potential doubling time of the tumour cells, from less than 1 to 8 days, occurs. The degree of vaginal spread of the tumour was directly related to the degree of parametrial involvement. The mean time taken for the vaginal component of the tumour to resolve following radiotherapy was related to its initial spread and the pre-treatment labelling index. The greater the spread of the tumour, the lower the labelling index and the longer the time taken for resolution. Up to 1 year following radiotherapy the incidence of locally recurrent, or metastatic disease was unrelated to the pre-treatment labelling index.

History and clinical findings of 18 cases of adenosquamous carcinoma of the skin appendages found among 135 cases of primary carcinoma of the vulva seen at the University of Minnesota Hospital between 1951 and 1970 were analyzed. In addition, two recent cases of this tumor were studied with conventional transmission electron microscopy. Adenosquamous carcinoma of the vulva showed poorer survival and a higher rate of lymph node metastases than squamous cell carcinoma of the corresponding stages (carcinoma in situ excluded). In four out of thirteen cases, the metastatic lesions in the lymph nodes retained glandular pattern. The ultrastructure showed mucin-producing columnar cells lining glandular lumina, and poorly differentiated squamous cells elsewhere; further, cells of the intermediate type between the two were present. This study indicates that adenosquamous carcinoma of the vulva is a distinctively separate entity from squamous cell carcinoma of the vulva, and possibly arises from mucin-producing cells of the skin appendages as suggested by Johnson and Helwig.

A total of 117 patients with microinvasive squamous carcinoma of the cervix encountered between 1960 and 1972 is reviewed. No lymph node metastases were found in the 42 patients who had pelvic lymphadenectomy and only one died from her disease. The proposal is made that when the depth of invasion is 3 mm or less, microinvasive carcinoma can be treated in the same way as carcinoma in situ.

Paraneoplastic neurologic syndromes in patients suffering from bronchial carcinoma were found by Croft and Wilkinson (Croft et al. 1965, Croft and Wilkinson 1965) in 16%. We examined the question whether in patients suffering from bronchial carcinoma neurologic syndromes are as frequent as in a comparative group of patients with different bronchial diseases. Out of 99 patients 61 had histological proof of bronchial carcinoma, 38 were suffering from chronic inflammatory bronchial diseases. The groups were statistically comparable to each other. Cases with carcinoma in situ (TINOMO) showed no significant difference from patients without bronchial carcinoma. In patients who showed intrathoracic metastases of lymphatic ganglions we found neurologic syndromes in 31% (p less than 0.01). Differing from the extension of tumor metastases there was no correlation between duration and frequency of neurologic syndromes. This corresponds to the experience of our hospital in the last 10 years; 5.7% of all patients with extracerebral tumors showed neurologic syndromes, most frequently polyneuropathies. In 10-15% of a normal population one can find these symptoms (Skre 1972), this means they are polygenetic. We did not find frequently an oat cell carcinoma in our material. Cases in which the neuromyopathy preceeded the manifestation of the bronchial carcinoma were not seen. Altogether it can be stated that paraneoplastic neuromyopathies in patients suffering from bronchial carcinoma are more seldom than it was to be assumed from the anglo-saxon literature.
