Colorectal cancer is predominantly a disease of the elderly population, but this disease is unusual in patients 40 years of age or under, and controversy persists as to prognosis in this subset of patients. The aim of this study was to determine the clinicopathologic features and their impact on patients survival of colorectal cancer in patients aged 40 years or younger, and to compare them with those of older patients. The records of 466 patients with non-metastatic colorectal adenocarcinoma who were referred between 1991 and 1999 to the University of Istanbul, Institute of Oncology, following curative surgery were retrospectively analysed. The clinicopathologic features of 84 (18%) colorectal cancers (group A; male:female ratio 48:36) which occurred in patients aged 40 years or younger were compared with 382 colorectal cancers in older patients (group B; male:female ratio 194:188). Patient gender, performance status, T stage, N stage, TNM stage, histologic grade, location of tumor, lymphatic invasion, serum levels of LDH and CEA, and survival rates were compared as prognostic factors. There was no statistically significant difference between group A and group B with respect to patient gender, performance status, T stage, N stage, TNM stage, histologic grade, location of tumor, serum levels of LDH and CEA, and survival rates of colorectal cancers. The proportion of lymphatic invasion was present in 27% of patients in group A vs. 12% in group B. With median follow-up of 69 months, the overall 5-year survival rate was 61% in group A and 56% in group B. In the univariate survival analysis according to age groups (group A and B), advanced TNM stage, location of rectal tumor, presence of lymphatic invasion, and presence of high serum LDH and CEA levels are predictors of poorer survival in young patients with colorectal cancer. In the Cox-Regression analysis, location of tumor and TNM stage were determined as independent prognostic factors for survival. This study revealed no difference in clinicopathologic characteristics in patients with colorectal cancer aged 40 years or younger compared with those aged above 40 years. However, in patients aged 40 years or younger, distal location of tumor and advanced stage should be considered as poor prognostic factors for overall survival.

CASE REPORTThe parents were descendants of the same great-grandparents (fourth generation). They denied knowledge of individuals in the family, other than their daughters, who had similar problems. Moreover, both parents and 5 of 9 maternal and paternal uncles and aunts were examined by us, and no additional cases were dliscovered. The pedigree and the HLA typing data (A, B, C, and DR) are shown in Figure 1. The HLA typing was performed on heparinized blood Figure 1, number 6), had limitation of movement of the wrists from birth. Later, she developed limitation of movement of the elbows, thumb deformities, an abnormal gait, and livedo reticularis of the legs. At the age of 12, she began to experience dyspnea on exertion. Pericarditis was diagnosed at another hospital; the condition did not respond to steroid therapy, and congestive heart failure developed. She underwent pericardiectomy at the age of 13, and the pathologic studies revealed chronic nonspecific pericarditis. When she presented to us, she had signs of congestive heart failure. She had flexion contractures of the interphalangeal joints of the thumbs, limited dorsiflexion of the wrists, and flexion contractures of the elbows and hips. The patient's asymptomatic siblings were called in for examination.Patient 2. This 14-year-old girl (Figure 1, number 7) had a history of trigger thumbs which resolved during her primary school years. At presentation, she had tenosynovitis of the wrists with limited dorsiflexion, flexion contractures of the elbows, limited internal rotation of the hips, synovitis of both knees, and limited plantar flexion of the ankles.Patient 3. This 13-year-old girl (Figure 1, number 8) exhibited camptodactyly of both fifth fingers and subluxation of the interphalangeal joint of the right thumb. In addition, she had limited movement of the wrists, flexion contractures of the elbows, limited movement of the hips, minimal synovitis of the knees, limited dorsiflexion of the feet, and livedo reticularis of the legs. Three years previously she had 2 bouts of acute pericarditis, separated by a few months. The

Anemia is common in patients with cancer and is a frequent complication of myelosuppressive chemotherapy. In this study, we investigated the incidence and severity of chemotherapy-induced anemia caused by the most common chemotherapy regimens, including the new generation of chemotherapeutic agents, used in the treatment of the major nonmyeloid malignancies in adults. Five hundred fifty-two patients with histologically proven carcinoma originating from breast (n = 165), lung (n = 128), colon (n = 75), ovary (n = 84), and malignant lymphoma (n = 100) were included in this study. Hemoglobin levels for each patient were measured with an automatic counter during both pretreatment and before each chemotherapy cycle during therapy. To document the incidence of anemia, the National Cancer Institute grading system was used. Before chemotherapy, 44% of patients with breast carcinoma had anemia. There was a 16% increase in the incidence of anemia after chemotherapy. Severe anemia was observed in less than 1% of patients. No difference was found in the incidence of anemia between the fluorouracil, doxorubicin, cyclophosphamide (FAC) and cyclophosphamide, methotrexate, fluorouracil (CMF) regimens used in the adjuvant setting. However, single-agent chemotherapy with newer generation caused more anemia when compared with the FAC regimen (p < 0.005). Chemotherapy resulted in a significant decrease in hemoglobin levels when compared with pretreatment values in patients with lung cancer (p < 0.001). During treatment, the increase in the incidence of grade II anemia was associated with a parallel decrease in the incidence of grade I anemia. The incidence of severe anemia did not exceed 15%. The incidence of anemia was equivalent in both patients with small-cell lung cancer and those with non-small-cell lung cancer treated with the etoposide and cisplatin (EP) combination. Seventy-one percent of patients with colon cancer had anemia before initiation of chemotherapy. No difference was observed in posttreatment hemoglobin values compared with pretreatment values. Patients treated with irinotecan and fluorouracil and leucovorin (FUFA) combination showed similar rates of anemia. Incidence of anemia in patients with ovarian cancer at admission was 68%. Chemotherapy resulted in a prominent increase in incidence of anemia, which increased to 91.5%. There was an increase in grade II anemia, which corresponded to the decrease in grade I anemia. Less than 10% of patients developed severe anemia. No difference in the incidence of anemia was observed in patients with ovarian cancer treated with either cisplatin and cyclophosphamide or cisplatin combination. Showing a high incidence of anemia (82%) at presentation, hemoglobin levels in patients with malignant lymphoma were unaltered with chemotherapy. Severe anemia occurred in less than 3% of patients. There was a higher incidence of anemia in patients with non-Hodgkin's lymphoma receiving the cyclophosphamide, epirubicin, vincristine, prednisone (CEOP) regimen in contrast to patients with Hod...
