This series characterized the clinico-pathologic features and outcome of patients with primary intestinal DLCL. While surgical resection in primary intestinal NHL seems beneficial, only prospective randomized studies can ascertain its precise role. Compared with patients with PG NHL, patients with primary intestinal disease had more prevalence of adverse prognostic features.

Pregnancy-associated breast cancer (PABC) is not a rare event. The association frequently imposes a management challenge. We intended to review the clinical features, therapy, and outcome of patients with PABC seen at a single institution over a five-year period and to compare those with that seen in a matched control group. Data of all patients with PABC diagnosed during pregnancy were retrospectively reviewed (Group I). For each patient in Group I, three matched controls with breast cancer without pregnancy were identified (matched for age, stage, and year of diagnosis, Group II). 72 patients in Group I and 216 in Group II were identified. Their median age was similar (34 vs 35 y, respectively). The median number of prior pregnancies for patients in Groups I and II was 5. Patients had shorter duration of symptoms prior to diagnosis as compared with their controls (5.6 vs 9.4 months, P < 0.0001). 3%, 31%, 40%, and 26% of patients had Stage I to IV, respectively. A pattern that was similar to that seen in our breast cancer population. Pregnancy was terminated in 34 patients (47%), while 38 (53%) had normal spontaneous vaginal delivery. 47 patients in Group I had surgery; 37 (52%) had modified radical mastectomy and 10 (14%) had conservative surgery. In 37 patients surgery was performed after termination of pregnancy and 10 had surgery performed during pregnancy. The median number of positive lymph nodes in Group I was 4 as compared with 2 for patients in Group II. No patients in Group I had systemic chemotherapy during first trimester, while only 4 (6%) and 3 (4%) received adjuvant or neoadjuvant during second and third trimester, respectively. No congenital malformation in the newborns was diagnosed. None of the patients in Group I received radiotherapy during pregnancy. Over a median of 47.5 months, 48 (67%) patients in Group I were alive as compared to 126 (58%) in Group II, with no difference in the median survival (P= 0.79). Comparing overall survival (OS) between the two groups stage for stage also showed no significant difference. Also there was no difference in progression-free survival between the two groups. Cox proportional hazard model identified advanced stage as the only independent adverse prognostic variable that influenced OS in Group I. Despite that this series included a relatively young population with a high fertility rate, the study confirmed the lack of a survival difference between patients with PABC and their matched controls.

The aim of this study was to identify the impact of various prognostic factors in the management of uterine sarcoma. Fifty-nine patients with uterine sarcoma were treated at King Faisal Specialist Hospital and Research Center between 1980 and 1997. Forty-three patients (73%) were treated by total abdominal hysterectomy and bilateral salpingo-oophorectomy, 7 (12%) total abdominal hysterectomy and bilateral salpingo-oophorectomy with sampling of pelvic lymph nodes, and 9 (15%) had biopsy only. Nine patients received adjuvant treatment; five had radiation therapy (XRT), two had chemotherapy, one had combined XRT and chemotherapy, and one received hormonal treatment. Leiomyosarcoma cases accounted for 42% of all the uterine sarcomas, carcinosarcoma cases for 34%, and endometrial stromal sarcoma (ESS) for 24%. Fifty (85%) patients had pathologic grade II and III tumor, with only 9 patients grade I. Twenty-seven patients (46%) were classified surgically as stage I, 7 (12%) as stage II, 17 (29%) as stage III, and 8 (13%) had stage IV tumor. Recurrences developed in 34 patients (71%). The 5- and 10-year overall actuarial survival for all patients was 42%, and the corresponding relapse-free survivals for those who achieved complete response after primary treatment (48 patients) were 27% and 20%. On the univariate analysis, grade I tumors (p = 0.04), ESS (p = 0.02), nonmetastatic stage (p = 0.05), and negative peritoneal cytology (p = 0.04) were associated with better overall survival.

This large series characterized the clinico-pathologic features and outcome of patients with DLCL PG-NHL. Performance status, and stage significantly influenced patient outcome. A prognostic index was developed and it identified three prognostically distinctive risk groups; however, prospective validation is warranted.

Loss to follow-up (LTFU) in cancer patients is a serious problem, yet there is little data on this and on the underlying reasons. Of 144 paediatric and 431 adult patients with lymphoma diagnosed in 1997/1998 at King Faisal Specialist Hospital and Research Center, Riyadh (KFSHRC), 30% and 48.5%, respectively, were LTFU after 4 years (excluding patients known to have died). In 2001-2002, 196 paediatric and adult lymphoma patients at KFSHRC were enrolled in a prospective study in which explanations were obtained in detail for non-attendance at follow-up appointments (No Show). Sixteen months after commencement of the study, 49 patients were No Show, because of patient-based communication problems (20), transportation problems (8), patient not contactable (18), and personal reasons (3). In addition, patients were recorded incorrectly as No Show through hospital/patient communication problems. The No Show patients, especially the 23 who failed to keep a second appointment, are identifiable as potential LTFU during the 3 years in which this cohort will be followed. This study and, we suggest, other studies on LTFU should stimulate interest in this issue, in the predisposing factors, and in strategies to address them.

A case-control study investigated the association between dietary fat and breast cancer in Saudi Arabian women attending a specialist hospital in Riyadh. Women with breast carcinoma [n= 499] newly diagnosed between 1996-2002, and control women [n = 498] randomly selected from patients’ attendants and relatives, completed a food frequency questionnaire. Serum levels of triglycerides and total cholesterol were measured. A significant positive association was found between risk of breast cancer and intake of fats, protein and calories. Adjusted odds ratios for the highest quartile of intake versus the lowest were 2.43 for saturated fat, 2.25 for animal protein, 2.12 for polyunsaturated fat, 1.88 for cholesterol and 2.69 for total energy from dietary intake. For serum triglycerides the adjusted odds ratio was 2.16 for the highest quartile
