Prevalence, associated factors, and relationship to quality of life of lower urinary tract symptoms: a cross-sectional, questionnaire survey of cancer patients.

BACKGROUND: Few studies conducted outside of Asia have shown that lower urinary tract symptoms (LUTS) could be a concern for cancer patients. This gap necessitates more research on LUTS among cancer patients in Asia, particularly regarding associated factors and the relationship between quality of life and LUTS. OBJECTIVES: This study investigates the prevalence, associated factors, and relationship to quality of life of LUTS based on a sample of cancer patients. DESIGN: A cross-sectional, questionnaire survey. SETTINGS/PARTICIPANTS: This study was conducted at two oncology outpatient departments in two hospitals in Taiwan, and included 134 Asian cancer patients. METHODS: We collected information about each participant's individual characteristics, personal habits, LUTS, and quality of life by using a questionnaire. We calculated descriptive statistics to demonstrate the distribution of collected information, and used multivariate logistic regression to identify the factors associated with LUTS. We used Student's t-test to compare the mean quality of life scores for participants with and without LUTS. RESULTS: Ninety-nine (73.9%) participants experienced at least one type of LUTS, and the prevalence rates for various types of LUTS ranged from 3.7% to 52.2%. Radiotherapy and the time since the diagnosis of cancer were associated with LUTS. Participants with LUTS reported lower quality of life scores than participants without LUTS. CONCLUSIONS: The high prevalence of LUTS suggests that cancer treatment might be linked to LUTS, which in turn has a negative effect on a patient's quality of life. These results suggest that future research should involve studies in larger, more homogeneous samples. Health care providers should monitor the presence of LUTS and deliver the management and treatments of LUTS to optimise cancer patients' quality of life.

Adjuvant sequential chemotherapy with doxorubicin plus cyclophosphamide, methotrexate, and fluorouracil (ACMF) with concurrent radiotherapy in resectable advanced breast cancer.

Doxorubicin (Adriamycin) is an anthracycline effective in breast cancer. Despite a worldwide acceptance of Adriamycin in the adjuvant chemotherapy to maximize the survival benefit in the higher risk patients with breast cancer with promising results, oncologists in general do not favorably consider anthracyclines in the adjuvant treatment setting because of concern about the acute and chronic drug-related toxicity. For high-risk patients with breast cancer with more than three positive axillary lymph nodes, this series adopted a modified sequential regimen of ACMF first with Adriamycin (A) as a single agent in 3-weekly administration for three courses, and then a combination of cyclophosphamide, methotrexate, fluorouracil (CMF) every 3 to 4 weeks for six courses given in an outpatient setting concurrent with radiation therapy as an adjuvant treatment. A total of 56 patients underwent modified radical mastectomy and 3 others breast conservation surgery for their invasive breast cancer. Forty-seven (84%) patients completed the intended adjuvant treatment and 1 patient died of infection from treatment-related neutropenia. As a whole, the 3-year overall survival and disease-free survival rates of 56 patients analyzed were 82.3% and 64.4%, respectively. In this high-risk group, patients with four to nine positive nodes showed a slightly better trend of survival than those with 10 or more positive nodes without reaching statistically significant difference (36-month overall survival: 90.9% vs. 72.5%, p = 0.06; disease-free survival: 78.7% vs. 47.8%, p = 0.38). In this entire group of patients, locoregional recurrence was absent. A total of 55 episodes of grade III and IV hematologic toxicity were observed, with only one death from neutropenic sepsis. This modified ACMF regimen offers a good survival rate in breast cancer patients with more than three positive axillary lymph nodes. When these patients are carefully managed, the morbidity and mortality related to the treatment are low.

Clinical characteristics of and response to combination chemotherapy and subsequent application of international prognostic index in non-Hodgkin's lymphoma--an experience from a medical center in Southern Taiwan.

A retrospective analysis was performed of 117 non-Hodgkin's lymphoma (NHL) patients (72 male and 45 female, mean age 55 years) treated at NCKUH between July 1988 and December 1993. Of the 115 patients who could be classified by Ann Arbor staging system, 26 patients (22.2%) were in stage 1; 23 (19.7%) in stage 2; 29 (24.8%) in stage 3; and 37 (31.6%) in stage 4. According to the International Working Formulation, three patients (2.6%) were low grade NHL, 90 (76.9%) were intermediate, and 8 (6.8%) were high grade NHL. Histologically, diffuse large cell NHL accounted for 52.1% of cases, followed by 16.2% of cases exhibiting diffuse mixed NHL. Immunophenotype analysis was available in 95 cases, which revealed 76 (80%) cases exhibiting B-cell origin, 17 (18%) cases exhibiting diffuse mixed NHL. Immunophenotype analysis was available in 95 cases, which revealed 76 (80%) cases exhibiting B-cell origin, 17 (18%) cases exhibiting T-cell origin and 2 (2%) cases were of null cell type. All patients underwent two groups of induction chemotherapy, either CHOP (Cyclophosphamide, Epirubicin, Oncovin, and Prednisolone), or "modified" COPBLAM (Cyclophosphamide, Epirubicin, Oncovin, and Prednisolone), or "modified" COPBLAM (Cyclophosphamide, Epirubicin, Oncovin, Vinblastine, Bleomycin, Procarbazine, and Prednisolone). Seventy-two cases treated through COPBLAM and 45 cases treated through CHOP were evaluated. The response rate (RR) to COPBLAM treatment was 72.2% and was 68.9% for the CHOP group (P = 0.51). The 5-year overall survival rate (OAS) was 44.1% for COPBLAM, versus 40% for CHOP (P = 0.15). The disease-free survival (DFS) was 72.6% at 63 months for COPBLAM and 58% at 51 months for CHOP (P = 0.16). Neither B cell nor T-cell lineages of NHL showed any statistical difference in RR (P = 0.53, DFS (P = 0.58) or OAS (P = 0.97) to the different treatments. Using multiple logistic analysis, two independent factors, high LDH and advanced stage, were found to adversely affect the rate of complete remission. The application of the International Prognostic Index to our patients needs modification, which suggests the necessity of more evaluation before it can accurately be applied to all international series of NHL.
