There is general evidence that the incidence of adenocarcinoma of the cervix has been rising, particularly among younger women. The determinants of these trends, however, remain largely unknown. We have reviewed the epidemiology of adenocarcinoma of the cervix using descriptive data from cancer registration and clinical series and two main sources of analytical data: clinical studies comparing cervical adenocarcinoma (AC) and squamous carcinoma (SC) and formal case-control and cohort epidemiological studies. In both the United States and northern Europe there is evidence of the rising frequency of AC in absolute and relative terms as compared to SC. These trends are generally restricted to younger women: under-age-35 AC incidence approximately doubled from the early 1970s to the early 1980s. Available data, although scanty, consistently show that the frequency of cervical adenocarcinoma rises with the number of partners and with decreasing age at first intercourse, suggesting a potential role for sexually transmitted (viral) factors. In clinical series, nulliparity was reported more frequently in AC than in SC cases but an inconsistent association was found in three formal epidemiological studies. Similarities with the epidemiology of endometrial cancer are also suggested from the association with overweight, while a possible relation with hypertension and diabetes is based on clinical series only and hence more difficult to interpret. Thus, adenocarcinoma of the cervix appears to share epidemiological characteristics with both adenosquamous cancer of the cervix and adenocarcinoma of the endometrium, although uncertainties in classification and registration leave several questions unanswered.

A 66-year-old Japanese woman with a rare acquired perforating disorder, usually called adult-type reactive perforating collagenosis, is reported. The patient had poorly controlled diabetes mellitus with retinopathy under oral diabetic medication. She was found to have multiple papules and umbilicated nodules on the trunk and four extremities when she was admitted and examined for the origin of jaundice and severe pruritus of sudden onset. In the biopsy specimen, collagen fibers were observed to be eliminated from the dermis through epidermal tunnel-like perforations. No elastic fibers were eliminated, and serial sectioning of the specimen could not prove follicular perforation. Adenocarcinoma of the biliary duct was found to be the cause of the jaundice with pruritus. Although such cases are usually classified as acquired reactive perforating collagenosis of adult onset, proposed reclassification for acquired perforating disorders is discussed. Another case which also showed perforation and transepithelial elimination of both collagen and elastic fibers as an incidental histologic finding is described. Such elimination seems to be a not uncommon step in the formation of pruriginous eruptions. Therefore, these cases should be differentiated from acquired-type characteristic perforating disorders.

Although a correlation has been suggested between cigarette smoking and pancreatic cancer, studies on pathological changes in the pancreas of smokers are fragmentary. In the present study we examined histopathologically 73 pancreases obtained by autopsy from 42 heavy cigarette smokers and 31 non-smoker patients. One invasive adenocarcinoma (2 cm in diameter) and three small carcinomas (2-5 mm in diameter) were found in smokers and one small carcinoma in a non-smoker patient. Although the incidence of pancreatic cancer in smokers was higher than in non-smokers, the difference was statistically not significant. Of smokers with pancreatic cancer, 2 had lung cancer, 1 skin cancer, 1 colon cancer and 1 was free of any malignancies. Ductal changes, including mucinous or squamous cell metaplasia and papillary hyperplasia, were found with equal frequencies in both groups of patients. The type and the incidence of these ductal alterations were not related to smoking but to the age. Our results do not indicate that cigarette smoking increases the incidence of pancreatic cancer, although, the limited number of the sections of the pancreas examined, as well as exclusion of other important variables, such as alcohol, diet and diabetes weaken the value of this study.

The results of 20 HLA 1-haploidentical donor kidney transplant patients treated with preoperative lymphocyte deletion through thoracic duct drainage and low dose of cyclosporine and steroid immunosuppressive therapy, were presented. The number of removed lymphocytes was 114 +/- 36 X 10(9) (mean +/- SD) and the duration of thoracic duct drainage was 35 +/- 7 days. Graft survival was 100% at 3-9 months and 89% at 1-2 years after transplantation. Patient survival was 100% at 3-9 months and 89% at 1-2 years. A patient died from lung cancer (adenocarcinoma) in the 9th posttransplant month. Acute rejection was not seen in 20 patients during the first 3 months. Life-threatening infectious disease was never seen either. Diabetes mellitus was observed in 1 patient. No other complications were observed. These results indicated that thoracic duct drainage and low dose cyclosporine and steroid postoperative immunosuppressive treatment might yield complete success in HLA 1-haploidentical kidney transplant patients.

The term "obstructive colitis" refers to ulceroinflammatory lesions occurring in the colon proximal to an obstructing or potentially obstructing lesion. We studied nine cases identified over a 9-month period. The patients were predominantly female (only one was male), elderly (mean age, 73), and usually had hypertension, diabetes, or other prior chronic illness. The colonic obstruction was due to adenocarcinoma in seven cases and to diverticular disease in two cases. Areas of colitis occurred either as circumscribed ulcers 0.5-2 cm in diameter (three cases) or as confluent circumferential lesions 8-25 cm in length; they were always separated from the more distal obstructing lesions by a segment of normal colon measuring 2.5-35 cm (mean, 14.6 cm). The involved area of colon was usually only mildly dilated; it exhibited moderate thickening of the wall and had a granular luminal surface accentuated in areas by deeper longitudinal or transverse ulcers. Often there were scattered pseudopolyps, and the margin separating the lesion from normal mucosa was well demarcated and irregular. In one case, two distinct separate areas of colitis were present; in another, the appendix was acutely inflamed. Microscopically, the lesions were composed of granulation tissue with a mixed acute and chronic inflammatory infiltrate that replaced the mucosa and often the submucosa; sometimes it extended into the muscularis propria, with associated peritonitis and perforation. Many of the features of obstructive colitis suggest an ischemic origin, probably mainly due to hypoperfusion following raised intramural pressure, but altered fecal flora may have a synergistic effect. The features of the disease are usually sufficiently characteristic to distinguish it from Crohn's disease and other forms of colitis. Complications include peritonitis, perforation and breakdown of anastomoses made through involved segments of colon that may appear externally normal at surgery.

The aim of this work is primary lung cancer in female population of the Doboj district in the period 1975-88. incidence research as well as age structure, localisation, histological types, stage and diseases associated with lung cancer. A group of 114 female patients was investigated and as comparative group male patients with lung cancer in the same period was used. The results show that incidence rate increase is significant and in the future that trend will be continued. Especially serious is often microcellular and adenocarcinoma appearance as well as female non-smoking patients (42%) and patients with diabetes mellitus (18%) in the investigated group high percentage. These phenomena lead to conclusion that risk factors are partly different and they should be better investigated. Females with diabetes mellitus require special treatment and further research should be focused on diabetes--lung cancer relationship.

This retrospective review of 37 cases of abdominoperineal resection for adenocarcinoma sought to correlate preoperative clinical characteristics and intraoperative events with the likelihood of subsequent development of specific complications in the postoperative period. Mortality was 3% (1/37), and the complication rate was 76% (28/37), with urologic (49% [18/37]) and pulmonary (30% [11/37]) complications being the most common. Significant perioperative risk factors included a history of cardiac disease, current cardiac medications, diabetes mellitus, an abnormal preoperative electrocardiogram, and extended operation. Factors not associated with an increased risk included age, sex, a history of pulmonary disorders, previous abdominal operations, operative time, and need for transfusions, management of the pelvic peritoneum, or perineal drainage. Such information should reliably identify high-risk patients and therefore should be useful for selecting such patients for palliative or other limited techniques of tumor control.

Endometrial carcinoma found in patients younger than 50 years of age were analyzed clinicopathologically in comparison with those of other age groups. The results were 1) Out of 150 patients with endometrial carcinoma, 44 (29.3%) were diagnosed in those younger than 50 years of age and 17(11.3%) were under the age of 40. The average age of endometrial cancer was 53.6 years and that of atypical endometrial hyperplasia was 49.2. 2) The majority of these patients (93.4%) had ever complained of vaginal bleeding, whereas those younger than 40 years of age had in 82.4%. 3) History of irregular menstrual cycle was only observed in 25.6% of the patients with the age 50 or older, whereas it was complained of in 61.5% of those among forties and in 56.3% of those younger than 40. 4) Nulliparity was found in 19.8% among 50 and older, whereas 70.4% and 64.7% were seen respectively in those among forties and younger than 40. 5) Hypertension was found more frequently in older patients, but diabetes mellitus and obesity did not correlate with age. 6) Seventy cases (46.7%) has history of receiving screening for cervical cancer without detecting endometrial cancer. 7) Well differentiated adenocarcinoma (G1) and adenoacanthoma was observed frequently in younger age group. Endometrial hyperplasia was often combined with cancer in young women. Having the data above mentioned, importance of screening for endometrial cancer in younger women is discussed.

For 81 cases of resectable pancreatic carcinoma, the site of cancer origin, cancer histologic features, and hyperplasia in the noninvolved duct were studied in relation to diabetes. They were classified into the following three groups: (1) fasting blood sugar (FBS) of less than 120 mg/dl (Group A, 26 cases); (2) FBS of more than 120 mg/dl with less than 2-year history of diabetes (Group B, 38 cases); and (3) FBS of more than 120 mg/dl with more than a 2-year history of diabetes (Group C, 17 cases). Although neither tumor size nor tumor location differed between the three groups, both the highest resectability (47%) and the lowest rate (71%) of extrapancreatic invasion were seen in Group C. A pancreatic ductogram showed that the pattern of the main pancreatic duct was intact in 0% in Group C versus 35% in Group A (P less than 0.05). Histologically, papillary/well-differentiated adenocarcinoma was present in 35% of Group A patients versus 61% of Group B and 71% of Group C patients (P less than 0.05). Papillary hyperplasia was present in the ducts of 27% of the patients in Group A; this was significantly lower than the other two groups. Atypical duct hyperplasia was present in 47% of Group C patients; this was significantly higher than in the other two groups. It appears that cells in the main pancreatic duct are vulnerable to hyperplastic and well-differentiated cancerous changes in patients with a history of diabetes of more than 2 years duration.

All cases of endometrial adenocarcinoma treated at the Geisinger Medical Center from January 1970 to June 1980 were retrospectively reviewed in an attempt to elucidate the clinical and pathologic profiles of the various histologic subtypes. Complete clinical and pathologic data was available in 418 cases of stage I endometrial adenocarcinoma. The frequency of the histologic subtypes were adenocarcinoma 66%, adenoacanthoma 16%, adenosquamous 5%, papillary 8%, clear cell 3%, and secretory 2%. Absolute 5-year survival was adenocarcinoma 88%, adenoacanthoma 91%, adenosquamous 62%, papillary 63% (P less than 0.01), clear cell 43% (P less than 0.001), and secretory 89%. When comparing the clinical and pathologic profile of the various histologic subtypes, adenosquamous (52%, P less than 0.001) and clear cell (43%, P less than 0.05) were associated with the highest percentage of grade 3 differentiation. Adenosquamous (38%, P less than 0.05) and clear cell (36%) also had the highest percentage of deep myometrial invasion. Papillary subtype (46%, P less than 0.05) was associated with the highest percentage of nulliparity. There was no difference among the subtypes when comparing menopausal status, exogenous estrogen, obesity, hypertension, diabetes, or uterine size. In summary, (1) adenocarcinoma and adenoacanthoma are the most frequent subtypes; (2) adenosquamous, papillary, and clear cell have decreased 5-year survival; (3) the decreased 5-year survival in adenosquamous and clear cell subtypes appears to be associated with increased grade 3 differentiation and deep myometrial invasion while the poor prognosis associated with papillary subtype was not related to grade or myometrial invasion.
