There are appreciable differences in total fluid intake at the individual and population level, and substantial difficulties in obtaining valid measures of fluid intake. Epidemiological studies have examined the association between fluid intake and different types of cancer. For bladder cancer, fluid consumption has been associated with a moderate increase of risk in some studies, including a multicentric case-control study from the United States, based on about 3000 cases, with a decrease in others, including the Health Professional Follow-up study, or with no material association. The evidence, therefore, is far from consistent. Sources and components of fluids were also different across different types studies. From a biological point of view, a decreased fluid intake could result in a greater concentration of carcinogens in the urine or in a prolonged time of contact with the bladder mucosa because of less frequent micturition. Carcinogenic or anticarcinogenic components of various beverages excreted in the urine may also play a role in the process. It has been suggested that fluid consumption has a favorable effect on colorectal cancer risk. Fluid intake may reduce colon cancer risk by decreasing bowel transit time and reducing mucosal contact with carcinogens. Low fluid intake may also compromise cellular concentration, affect enzyme activity in metabolic regulation, and inhibit carcinogen removal. However, epidemiological data are inadequate for evaluation. Data are sparse and inconsistent for other neoplasms, including breast cancer. The fluid constituent of foods, confounding, interactions and possible influences of specific types of beverages should be investigated further. In conclusion therefore the association between total fluid intake and cancer risk remains still open to debate.

Radical radiotherapy is a standard form of management of localised prostate cancer. Conformal treatment planning spares adjacent normal tissues reducing treatment-related side effects and may permit safe dose escalation. We have tested the effects on tumour control and side effects of escalating radiotherapy dose and investigated the appropriate target volume margin. After an initial 3-6 month period of androgen suppression, 126 men were randomised and treated with radiotherapy using a 2 by 2 factorial trial design. The initial radiotherapy tumour target volume included the prostate and base of seminal vesicles (SV) or complete SV depending on SV involvement risk. Treatments were randomised to deliver a dose of 64 Gy with either a 1.0 or 1.5 cm margin around the tumour volume (1.0 and 1.5 cm margin groups) and also to treat either with or without a 10 Gy boost to the prostate alone with no additional margin (64 and 74 Gy groups). Tumour control was monitored by prostate-specific antigen (PSA) testing and clinical examination with additional tests as appropriate. Acute and late side effects of treatment were measured using the Radiation Treatment and Oncology Groups (RTOG) and LENT SOM systems. The results showed that freedom from PSA failure was higher in the 74 Gy group compared to the 64 Gy group, but this did not reach conventional levels of statistical significance with 5-year actuarial control rates of 71% (95% CI 58-81%) in the 74 Gy group vs 59% (95% CI 45-70%) in the 64 Gy group. There were 23 failures in the 74 Gy group and 33 in the 64 Gy group (Hazard ratio 0.64, 95% CI 0.38-1.10, P=0.10). No difference in disease control was seen between the 1.0 and 1.5 cm margin groups (5-year actuarial control rates 67%, 95% CI 53-77% vs 63%, 95% CI 50-74%) with 28 events in each group (Hazard ratio 0.97, 95% CI 0.50-1.86, P=0.94). Acute side effects were generally mild and 18 weeks after treatment, only four and five of the 126 men had persistent > or =Grade 1 bowel or bladder side effects, respectively. Statistically significant increases in acute bladder side effects were seen after treatment in the men receiving 74 Gy (P=0.006), and increases in both acute bowel side effects during treatment (P=0.05) and acute bladder sequelae (P=0.002) were recorded for men in the 1.5 cm margin group. While statistically significant, these differences were of short duration and of doubtful clinical importance. Late bowel side effects (RTOG> or =2) were seen more commonly in the 74 Gy and 1.5 cm margin groups (P=0.02 and P=0.05, respectively) in the first 2 years after randomisation. Similar results were found using the LENT SOM assessments. No significant differences in late bladder side effects were seen between the randomised groups using the RTOG scoring system. Using the LENT SOM instrument, a higher proportion of men treated in the 74 Gy group had Grade > or =3 urinary frequency at 6 and 12 months. Compared to baseline scores, bladder symptoms improved after 6 months or more follow-up in all groups. Sexual function deteriorated after treatment with the number of men reporting some sexual dysfunction (Grade> or =1) increasing from 38% at baseline to 66% at 6 months and 1 year and 81% by year 5. However, no consistent differences were seen between the randomised groups. In conclusion, dose escalation from 64 to 74 Gy using conformal radiotherapy may improve long-term PSA control, but a treatment margin of 1.5 cm is unnecessary and is associated with increased acute bowel and bladder reactions and more late rectal side effects. Data from this randomised pilot study informed the Data Monitoring Committee of the Medical Research Council RT 01 Trial and the two studies will be combined in subsequent meta-analysis.

A case of bladder squamous cell cancer producing granulocyte colony-stimulating factor (G-CSF) is reported. A 55-year-old female presented with macroscopic hematuria and urinary frequency. Cystoscopy demonstrated a large bladder tumor. Computerized tomography and magnetic resonance imaging of abdomen and pelvis showed bladder muscular invasion, but did not reveal any metastasis. Laboratory examination showed leukocytosis of 23,600/mm3 and a high value of granulocyte colony-stimulating factor (G-CSF) 77 pg/ml in the peripheral blood. She was diagnosed with bladder tumor 52 months ago, but did not seek further medical attention. The leukocyte count at that point was 10,700/mm3. Radical cystectomy was performed. The histopathological diagnosis was well differentiated squamous cell carcinoma. Immunohistochemical examination was positive for G-CSF. After surgery the leukocyte count and value of G-CSF in the peripheral blood decreased to the normal range. There has been no recurrence of cancer for 10 months after surgery without any adjuvant therapy.

The spectrum of renal tract infections is wide. When the kidney has been severely damaged, the radiological findings may suggest a malignancy. To report a case of chronic pyonephrosis, which even at exploration appeared to be a malignancy. The case record of the patient as well as the literature were reviewed and reported. A 25 year-old woman presented with a 5-year history of left lumbar pain, urinary frequency and intermittent total haematuria. The intravenous urography showed non-function in the left kidney harbouring a calculus. Treatment was delayed for poor finances. At laparotomy a huge renal mass invading the colonic mesentery and showing neovascularisation was removed. The final diagnosis was chronic pyonephrosis. She recovered from postoperative septicaemia. Neovascularisation is a feature of malignant disease mediated by angiogenesis factors. These factors are probably present in chronic inflammation. It is suggested that for nephrectomy, prophylactic antibiotics should be used. There is also a need for histopathological examination of every specimen removed at operation.

A 57-year-old woman visited a physician with complaints of anorexia and pollakiuria. Because a pelvic tumor and ascites were detected, she was referred to our department. Douglas pouch puncture revealed adenocarcinoma cells. Further examination showed an advanced gastric cancer with peritoneal dissemination. The cancer was judged to be unresectable. Chemotherapy with a combination of TS-1 and CDDP was performed before the operation. After 2 courses of the chemotherapy, her complaints disappeared, although abdominal CT confirmed remaining peritoneal dissemination. After 7 courses of chemotherapy, abdominal CT showed that the peritoneal dissemination had disappeared. Total gastrectomy and lymph node dissection were performed. Histological findings of the stomach revealed complete disappearance of cancer cells in the stomach and the regional lymph nodes. We confirmed that the TS-1/CDDP therapy resulted in a complete response to advanced gastric cancer and peritoneal dissemination. We recommend that chemotherapy be continued until the peritoneal dissemination disappears.

Malakoplakia represents a chronic inflammatory disease associated with a broad spectrum of bacterial infections. On histopathology, Michaelis-Gutmann bodies are considered as pathognomonic histopathological findings. Rarity of the disease and wide variety of clinical presentation makes its diagnosis very challenging. We report herein the case of a 66-year-old woman who, having undergone lower anterior resection for rectal adenocarcinoma 3 and a half years ago, presented with urinary frequency and dull abdominal pain. CT scan revealed a soft tissue tumour infiltrating the preperitoneal fat over the urinary bladder, which was considered as recurrence of the rectal carcinoma. On laparotomy, a tumour invading the bladder, small intestine and the anterior abdominal wall was resected and the patient recovered uneventfully. On histopathology, malakoplakia of urinary bladder was revealed. Overstaging of patients' malignancy due to malakoplakia is not uncommon, so its early identification can help avoid incorrect treatment.

This international study aimed to test the measurement properties of the updated European Organisation for Research and Treatment of Cancer (EORTC) questionnaire module for colorectal cancer, the QLQ-CR29. The QLQ-CR29 was administered with the QLQ-C30, core questionnaire, to 351 patients from seven countries. Questionnaire scaling and reliability were established and clinical and psychometric validity examined. Patient acceptability and understanding were assessed with a debriefing questionnaire. Multi-trait scaling analyses and face validity refined the module to four scales assessing urinary frequency, faecal seepage, stool consistency and body image and single items assessing other common problems following treatment for colorectal cancer. Scales distinguished between clinically distinct groups of patients and did not correlate with QLQ-C30 scales, demonstrating construct validity. The QLQ-CR29 scores were reproducible over time in stable health. The EORTC QLQ-CR29 demonstrates sufficient validity and reliability to support its use to supplement the EORTC QLQ-C30 to assess patient-reported outcomes during treatment for colorectal cancer in clinical trials and other settings.

The bladder is a hollow visco-elastic organ involved in urinary continence. In relation to its anatomical location, bladder is exposed in whole or in part to ionizing radiation in external radiotherapy or in brachytherapy of the pelvic region. The acute and late functional changes after external beam radiation consist in urinary frequency, compliance defaults and hematuria. Incidence of urinary side-effects, as well as related modalities of radiotherapy, is poorly described in the literature. Medline literature searches were performed via PubMed using the keywords "bladder--radiotherapy--toxicity--radiation cystitis--tolerability--organ at risk" to describe urinary side-effects due to radiation. Some recommendations exist on the dose constraints applied to bladder. These were mainly established from prostate radiation therapy studies but without definitive consensus. In clinical practice, dose constraints take into account clinical settings: bladder cancer which requires total bladder irradiation or others pelvic tumours (prostate, uterus...) in which the bladder is considered as an organ at risk. Risks of radiation cystitis increase with total dose (above 60 Gy), bladder irradiated volume and concomitant chemoradiation. Modern techniques using conformal radiotherapy with modulated intensity will probably have beneficial impact on bladder toxicity.

Adenocarcinoma of the vermiform appendix is a rare disease that constitutes less than 0.5% of all gastrointestinal malignancies. A patient was admitted with abdominal discomfort and urinary frequency but no symptoms suggestive of enterovesical fistula, e.g. pneumaturia or urinary tract infection. She was diagnosed with adenocarcinoma of the appendix with a fistula to the urinary bladder.

Xanthogranulomatous cystitis is a rare, benign, chronic inflammatory disease of the bladder, mimicking malignancy with unknown etiology. Herein, we report a 57-year-old man who presented with pollakiuria, nocturia, dysuria, left flank pain, and a palpable mass on the right lower abdomen. Computerized tomography demonstrated an obstructing 10-mm stone in the lower third of the left ureter and a 6-cm solid mass on the right at the anterolateral wall of the bladder. The mass presented local perivesical invasion at the anterolateral side. Cystouretroscopy revealed a mass protruding into the bladder cavity with edematous smooth surface. Frozen section analysis of the partial cystectomy specimen could not rule out malignancy. Therefore, radical cystoprostatectomy and ureterolithotomy were performed. Histologically, fibrosis, numerous plasma cells, eosinophils, and, immunohistochemically, CD68-positive epithelioid and foamy macrophages were detected. Localized prostatic adenocarcinoma was also found. The present case of xanthogranulomatous cystitis is the 23rd to be reported in the world literature.
