A 24-year-old Japanese man presented with dyskeratosis congenita (DC, Zinsser-Cole-Engman syndrome) complicated by non-cirrhotic portal hypertension, signet ring carcinoma of the rectum and Pneumocystis carinii pneumonia. At the age of 9 years, he was diagnosed as having DC on the basis of typical clinical manifestations including atrophic lingual papillae, hyperpigmentation of the skin, thrombocytopenia, and ophthalmological abnormalities. A few years later pancytopenia and splenomegaly developed. At 24 years, signet ring carcinoma of the rectum was detected but could not be resected because of the severity of the pancytopenia. Death was due to respiratory failure from P. carinii pneumonia. At autopsy the case illustrated several unique findings for DC, including non-cirrhotic portal hypertension, atrophy of frontal lobe and markedly slender folia of the cerebellum and superimposed infections with herpes zoster virus and P. carinii. Striking lymphocyte depletion and atrophy of lymphoid parenchyma in lymph nodes, tonsils, spleen, gastrointestinal tract, or thymus were seen histologically. The morphological picture supports the suggestion that there is a defect in the cell-mediated immune system in patients with DC, although immunoglobulin levels in the blood are normal. The cell-immune deficiency is a major factor in the poor prognosis.

The treatment of early rectal (T1) adenocarcinoma is controversial. Between 1974 and 1985, nine patients underwent local excision of rectal cancer followed by radiation therapy (RT) at the University of Florida. All cancers were exophytic and less than or equal to 3 cm in diameter. Pathologically, all tumors were adenocarcinomas, Broder Grade I or II. Surgical margins were free of tumor in eight of nine (89%) specimens. Eight of nine (89%) cancers were confined to the submucosa and one cancer invaded the muscularis propria. All patients received a minimum 4500 rad with or without a boost of an additional 1000 to 1500 rad. There were no operative deaths and the morbidity was minimal. Follow-up ranged from 24 to 127 months (mean 64). Twelve months following treatment one patient died of pneumonia, with no evidence of disease (NED). Eight patients remain NED (mean 67 months) at the time of this study.

From 1981 to 1994, intra-operative radiotherapy after subtotal cystectomy was performed on 22 patients with invasive bladder carcinoma on whom radical cystectomy could not be recommended because of old age or condition. All the patients received 25 to 30 Gy of radiotherapy focused on trigonum and internal urethral orifice after subtotal cystectomy with uretero-cutaneostomy. Of 22 patients, 15 patients died. Five patients died of bladder cancer, one died of gastric cancer, one died of rectal cancer and the others died of pneumonia, heart failure, sepsis and senility. The five-year survival rate was 41% and the cause-specific five-year survival rate was 75%. Local recurrence was seen only in one patients, who received second intra-operative radiotherapy and recovered well in complete remission. We believe that intra-operative radiotherapy after subtotal cystectomy is useful for patients with invasive bladder carcinoma on whom radical cystectomy could not be recommended because of old age or condition.

The life expectancy of women currently exceeds that of men by almost seven years, yet women spend approximately twice as many years disabled prior to death as their male counterparts. The diseases that account for death and health care utilization in older women (heart disease, cancer, stroke, fracture, pneumonia, osteoarthritis, cataracts) are also major contributors to disability. This paper reviews the scientific evidence that supports specific recommendations for older women that may prevent or delay these conditions for as long as possible. Risk factors for falls and fractures should be assessed and, where possible, modified. Adequate intakes of calcium, vitamin D, fruits, and vegetables should be encouraged. Weight should be monitored and weight loss discouraged for most women. Screening for B12 deficiency is recommended. Engaging women in a shared decision-making process about the use of hormone replacement therapy for longterm prevention of heart disease and fractures is important, as is regular screening for breast and colo-rectal cancer. Women should be encouraged to engage in enjoyable physical activities, including walking, for 30 minutes daily. These interventions have the potential to delay the onset and improve the course of many chronic conditions that prevail in later life.

A 73-year-old man with colon cancer had been treated elsewhere for pneumonia on June 12, 1994. He was admitted to our hospital on June 21 with progressive dyspnea and bilateral diffuse infiltrates on chest X-ray. On admission, plain chest radiographs and chest CT scans revealed bilateral interstitial shadows predominantly in the outer zone, of the lower lobes. After an operation for rectal cancer, he had begun taking orally 300 mg of fluorouracil daily for 64 days. A drug lymphocyte stimulation test (DLST) was positive for fluorouracil. Fluorouracil-induced pneumonitis was subsequently diagnosed. To the best of our knowledge, there have been no previous case reports of fluorouracil-induced pneumonitis, and it seems likely that this pneumonitis resulted from both toxic and allergic reactions to the drug.

Pseudomyxoma peritonei (PMP) is an unusual form of intraabdominal neoplasm that produces a large amount of extracellular mucin. It is often associated with mucinous tumors of gastrointestinal tract or ovary. Herein, we report 3 patients with pseudomyxoma peritonei with high serum carbohydrate antigen 19-9 (CA19-9) levels. The first patient, who had a CA19-9 level of 1132 U/ml, had well-differentiated rectal cancer and died of chemotherapy complications, pneumonia and septic shock; one month after admission. The other 2 cases with CA19-9 levels of 2520 U/ml and 679 U/ml had tumors of unknown origins and had survived more than 1 year and 3 months after treatment, respectively. Usually, elevated serum CA19-9 levels are found in patients with pancreatic, biliary, colorectal, gastric or liver cancers. However, many studies have shown high serum CA19-9 levels are associated with mucinous carcinoma. Immunochemical studies also showed positive staining of CA19-9 in mucinous tumors. PMP is composed of large amounts of mucin, therefore, we suggest that serum and ascites CA19-9 levels should be routinely checked in patients with PMP.

Cancer-associated acute disseminated intravascular coagulation is rare in colorectal cancer, but is rapidly fatal when present. We present a case of a 79-year-old male who developed acute disseminated intravascular coagulation one month after receiving Hartmann's procedure for his rectal cancer. Peripheral blood showed leucoerythroblastosis while marrow carcinomatosis was noted by bone marrow examination. Prompt chemotherapy with weekly 24-h infusion of 5-fluorouracil and leucovorin were administered and the acute disseminated intravascular coagulation gradually resolved after 2 cycles of treatment. A total of 10 cycles of weekly chemotherapy were administered. The patient died of pneumonia on the 83rd day after diagnosis of disseminated intravascular coagulation without evidence of acute disseminated intravascular coagulation and tumor progression. We suggest that if acute disseminated intravascular coagulation developed after surgery for rectal cancer, the cancer-related acute disseminated intravascular coagulation should be taken into consideration. The immediate administration of chemotherapy may save the patient in time.

The aim of this study was to investigate the efficacy and safety of chemoradiation using capecitabine and irinotecan as neoadjuvant therapy for patients with rectal cancer. Conventional radiation was given at daily fractions of 1.8 Gy on 5 days a week for a total dose of 55.8 (50.4 + 5.4) Gy. Concurrently, irinotecan 40 mg m(-2) once weekly and capecitabine continuously at dose levels of 500, 650, 750 and 825 mg m(-2) twice daily were administered. Surgery was performed 4-6 weeks following completion of chemoradiation. A total of 28 patients (3 UICC II, 25 UICC III) were enrolled and all received treatment. Dose-limiting toxicity was diarrhoea grade IV and hand-foot syndrome at the 825 mg m(-2) dose level. The maximum tolerated dose of capecitabine was 750 mg m(-2). Diarrhoea was the most common toxicity: grade III in nine patients. Two patients died, one due to pneumonia and one due to sudden cardiac death. A complete response and only microfocal residual tumour disease was achieved in four and three patients (27%). In all, 25 of 28 patients undergoing surgery, 24 (96%) had R0 resection. Preoperative chemoradiation based on continuous daily capecitabine and weekly irinotecan appears to tolerated and effective in patients with rectal cancer.

The patient presented here is a 30-year-old woman who underwent anterior resection for the initial treatment of rectal cancer. A postoperative study showed a single liver metastasis. The patient received adjuvant pelvic radiotherapy with concomitant 5-fluorouracil (5-FU) treatment followed by liver metastasectomy 6 weeks after the completion of radiation therapy and chemotherapy. Adjuvant therapy with 5-FU, leucovorin, and oxaliplatin (FOLFOX 4 regimen) was continued. The initial five cycles were well tolerated with the occurrence of only paresthesia that did not interfere with function. After the sixth cycle of the treatment, progressive dyspnea and persistent cough developed in the patient, although her clinical history was negative for lung disease. A chest radiograph revealed diffuse bilateral interstitial infiltrates, and a chest CT scan showed bilateral alveolar infiltrates predominant in the right lung. Lung biopsy by video-assisted thoracoscopy was performed, and the histologic report showed cryptogenic organizing pneumonitis (COP). Prednisone therapy (1 mg/kg/d) resulted in a very good clinical response. In fact, the patient had complete remission of respiratory symptoms including cough and dyspnea after 4 days of treatment, and the chest CT scan showed complete resolution of lung infiltrates after 4 weeks. One month later, the patient continued adjuvant treatment with six cycles of 5-FU, leucovorin, and irinotecan (ie, the FOLFIRI regimen) without complications. Thus, oxiplatin was implicated as the likely cause of this drug-induced lung toxicity, which is a very rare complication associated with platins. Diffuse interstitial lung disease, particularly COP, has been described following the administration of the cytotoxic agents bleomycin and busulfan, but a connection to oxaliplatin has not been reported before this case.

Pathologic complete response (pCR) to neoadjuvant chemoradiation (CRT) in patients with rectal cancer is associated with improved prognosis, whereas postoperative surgical complications have been linked with poor oncologic outcomes. Our objective was to examine the association between postoperative complications and pCR. We analyzed 127 patients enrolled in a prospective multicenter study investigating rectal cancer response to CRT. Surgical complications were scored according to the Clavien-Dindo scale (Grade 1 to 4). Among the 127 patients analyzed, 28 (22%) patients had a pCR. In the pCR group, six surgical Grade 3+ complications occurred in five (18%) patients, including anastomotic leak (n = 2), ureteral injury (n = 2), pelvic abscess (n = 1), and pneumonia (n = 1). In the non-pCR group, there were 10 Grade 3+ complications in eight (8%) patients, including severe obstruction (n = 1), postoperative hemorrhage (n = 1), leak (n = 2), pelvic abscess (n = 2), ureteral injury (n = 1), and severe morbidity (stroke, n = 1; acute respiratory distress, n = 1; and cardiac event, n = 1). There was no significant difference in the frequency of total surgical complications between pCR and non-pCR patients; and no association was observed between pCR and major postoperative complications. In conclusion, postoperative complication rates do not differ between pCR and non-pCR groups. The occurrence of major postoperative complications is not associated with response to neoadjuvant CRT.
