A case of synchronous double primary cancers of prostate, and bladder in a hemodialysis patient: a case report

A 60-year-old male, who had been maintained on hemodialysis for 4 years, visited our hospital to receive living renal transplantation. He complained of macrohematuria, and preoperative examination showed elevation of psostate specific antigen (PSA). Cystoscopy revealed papillary tumors on the right lateral bladder wall. Transurethral resection of bladder tumor (TUR-Bt) was performed and histopathological examination showed transitional cell carcinoma, G2, pTa. The histologic diagnosis of the transrectal needle prostate biopsy specimen was moderately differentiated adenocarcinoma. Combined androgen blockade as a neoadjuvant therapy and radical prostatectomy were performed. A case of synchronous double primary cancers, comprised of adenocarcinoma of the prostate and transitional cell carcinoma of the urinary blader in a hemodialysis patient has never been previously reported in the Japanese literature.     

Double primary malignant neoplasm of renal cell carcinoma and stomach cancer: report of two cases

Two cases of double primary malignant neoplasm of renal cell carcinoma and gastric cancer are presented. Case 1 was a 59-year-old woman with right renal cell carcinoma (granular cell subtype) and gastric cancer (poorly differentiated adenocarcinoma). Case 2 was a 72-year-old man with left renal cell carcinoma (clear cell carcinoma) and gastric cancer (tubular adenocarcinoma). In both cases, the occult blood reactions of stool was strong and clear gastrointestinal symptoms developed. In these 2 cases of synchronous double cancer, gastrectomy following nephrectomy was performed in the same operation.     

Synchronous triple urogenital cancer (renal cancer,bladder cancer,prostatic cancer): a case report

A case of synchronous triple urogenital cancer, which was comprised of renal cell carcinoma of the left kidney, transitional cell carcinoma of the urinary bladder, and adenocarcinoma of the prostate, is reported. A 72-year-old Japanese male patient was referred to our outpatient clinic with the complaint of asymptomatic hematuria. At that time, his serum of level of PSA was elevated to 20 ng/ml. Cystourethroscopy showed a papillary bladder tumor and coagula through the left urinary orifice. Ultrasonography, computed tomography and magnetic resonance imaging showed a mass lesion measuring about 6 cm by 5 cm in the left kidney. Angiography showed a hypervascular lesion measuring about 6 cm by 5 cm at the same site. Double cancer, consisting of renal cell carcinoma and transitional cell carcinoma of the urinary bladder, was suspected and we performed left total nephroureterectomy, hilar lymphadenectomy, and transurethral rection of the bladder tumor, one month later. At the same time, we performed a biopsy of the prostate. Histological diagnosis was renal cell carcinoma, clear cell carcinoma and transitional cell carcinoma of urinary bladder. Histological diagnosis of the prostate biopsy was moderately differentiated adenocarcinoma. Since this case fulfilled the criteria of Warren and Gates, it was classified as synchronous triple urogenital cancer. A review of the literature revealed 17 authentic cases of triple urogenital cancer, of which 14 and 10 cases were reported as a combination of renal cancer, bladder cancer and prostatic cancer, in the world and in Japan, respectively. Furthermore, he had been exposed to the atomic bomb explosion in Hiroshima in 1945. This carcinogenic precursor may be related to the development of the triple cancer.     

Carcinoma of the urachus--report of 4 cases

Four cases of urachal carcinoma are presented. The first case was a 36-year-old man who was admitted with the chief complaint of macrohematuria with mucinous debris. Cystoscopic examination revealed a single tumor at the dome of the bladder. Partial cystectomy and postoperative radiation therapy were performed. Histological findings showed a well differentiated adenocarcinoma. He has been well for twelve years postoperatively. The second case was a 52-year-old man who was admitted with the chief complaint of macrohematuria with mucinous debris. Cystoscopic examination revealed a single tumor at the dome of the bladder. Partial cystectomy and postoperative radiochemotherapy were performed. Histological findings showed a moderately differentiated adenocarcinoma. He died of a recurrent tumor 30 months after operation. The third case was 70-year-old man who was admitted with the chief complaint of macrohematuria with mucinous debris. Cystoscopic examination revealed multiple tumors at the dome of the bladder, internal urethral orifice and right lateral wall. Total cystectomy, ureterocutaneostomy and postoperative chemotherapy were performed. Histological findings showed a poorly differentiated adenocarcinoma. He died of a recurrent tumor 30 months after operation. The fourth case was a 68-year-old woman who was admitted with the chief complaint of macrohematuria with mucinous debris. Cystoscopic examination revealed a single tumor at the dome of the bladder. CT scan demonstrated a mass with calcification extending from the bladder dome superiorly. Partial cystectomy and postoperative chemotherapy were performed. Histological findings showed a well differentiated adenocarcinoma. She has been well for three months postoperatively.(ABSTRACT TRUNCATED AT 250 WORDS)     

Metastatic renal tumors: clinical report of three cases and review of 136 cases including 38 cases from the Japanese literature

Three cases of metastatic renal tumor are reported. The first case was of a 61-year-old man, who had a Miles' operation for rectal adenocarcinoma 30 months before, and suffered from high fever and right flank pain. Right nephrectomy was carried out and the kidney was found to contain an adenocarcinoma identical to the one previously removed from the rectum. He died 1 year after nephrectomy. The second case was of a 35-year-old man, who had undergone left pneumonectomy for a squamous cell carcinoma of the bronchus. One month later, he was readmitted with cloudiness of consciousness and high fever. Investigations revealed right kidney, adrenal gland and brain malignancies, and which were ectomized totally. On pathological examination all ectomized tissues were metastatic squamous cell carcinoma. He died 1 month after the second operation. The third case was of a 48-year-old man, who had undergone left pneumonectomy for a squamous cell carcinoma of the bronchus. One year after pneumonectomy, abdominal CT showed a left renal tumor. Right nephrectomy was performed and pathological examination revealed a metastatic squamous cell carcinoma. He is now alive 4 months after nephrectomy without any sign of recurrence. A total of 136 cases of metastatic renal tumors including 38 cases from the Japanese literature, are reviewed.     

A case of synchronous triple primary carcinomas of the kidney,bladder and prostate

A case of synchronous triple carcinomas arising in the kidney, bladder and prostate is reported. An 82-year-old man had gross hematuria. Urine cytology was positive and intravenous pyelography showed right hydronephrosis with a filling defect in the bladder. Computed tomography revealed a 4 cm mass in the bladder, enlarged prostate and 6 cm renal mass at the left kidney. Cystoscopy demonstrated a papillary broadbased tumor with some small satellite tumors in the bladder, and magnetic resonance imaging revealed muscle invasion of the bladder tumor. This patient underwent left radical nephrectomy and total cystoprostatectomy with ileal conduit urinary diversion as radical treatment. Histological diagnosis was renal cell carcinoma, transitional cell carcinoma of the bladder. Furthermore, well-differentiated adenocarcinoma was found incidentally in the prostate. Immunohistochemical staining with anti-p53 antibody for the three tumors showed positive staining only for the bladder cancer.     

Pulmonary pleomorphic carcinoma; report of 2 cases

The 1st case was a 74-year-old male diagnosed as femoral neck fracture. Biopsy of the bone revealed metastatic adenocarcinoma. Chest computed tomography (CT) showed a mass lesion located in the right lower lobe. With a diagnosis of primary lung cancer (cT2N1M1), two-staged operation was performed. Pathological diagnosis was pleomorphic carcinoma [pT2N1M1 (OSS), stage IV]. He died 8 months after surgery due to metastasis to the thoracic spine. The 2nd case was a 80-year-old female who complained of lateral chest pain. Chest CT revealed a tumor in the right hilar region, which was diagnosed as adenocarcinoma by transbronchial lung biopsy. Only thoracic drainage was performed since metastases to the brain and the rib were demonstrated. She died 2 months after admission. Autopsy revealed pleomorphic carcinoma of the lung with metastasis to the brain, costa and mediastinal lymph nodes.     

A case of primary transitional cell carcinoma of the prostate

A 77-year-old man was referred to our hospital with a complaint of dysuria and right ischiodynia. He had had a hemi-thyroidectomy for thyroid cancer and right cervical lymphadenectomy three years and one year, respectively, before this visit. Prostate cancer was strongly suspected by transrectal examination with prostate specific antigen (PSA) elevated to 77.8 ng/ml. Pathological diagnosis of prostate biopsy specimen was transitional cell carcinoma with grade 3 malignancy and negative staining for PSA. Endoscopic examination showed a normal appearance of bladder and prostatic urethral epithelium. Urine cytology showed no malignant cells. However, immunostaining for PSA revealed that the cervical lymph node specimen resected before was moderately differentiated adenocarcinoma of prostate. He had multiple metastases to mediastinal and retroperitoneal lymph nodes and right ischium. Endocrine therapy (goserelin acetate depot, bicalutamide) and systemic chemotherapy (methotrexate, epirubicin, cisplatin) were performed combined with irradiation to right ischium metastasis. Two months later, he showed a complete response in PSA and partial response in lymph node metastases, but died of cancer 13 months later.     

Small cell carcinoma of the prostate: a report of three patients and a prognostic analysis of cases reported in Japan

Small cell carcinoma (SCC) originating from the prostate is rare. We report three cases of SCC of the prostate. Case 1: A 29-year-old man with large pelvic mass and pelvic lymph node metastases was diagnosed as having pure SCC of the prostate. Chemo-radiotherapy resulted in a great reduction of the tumor volume. However, the disease recurred immediately, and he died of disease 17 months after diagnosis. Case 2: A 65-year-old man presented with pure prostatic SCC with lung metastases. Although cystoprostatectomy combined with pre- and post-operative chemotherapy ended with no evidence of disease, he died after 16 months because of multiple metastases and local recurrence. Case 3: A 73-year-old man was diagnosed as having SCC and poorly differentiated adenocarcinoma of the prostate simultaneously. Chemo-endocrine therapy and pelvic irradiation were performed, achieving partial remission. However, he developed multiple distant metastases, and died of disease 15 months after diagnosis. We reviewed 82 cases previously reported in Japan. Patient's ages ranged from 24 to 86 years (mean 68.7 years). Many patients had lymph node or distant metastases (stage D, 73%). Thirty-seven (45%) were pure SCCs and 45 (55%) were associated with adenocarcinoma. The prognosis after the recognition of SCC is very poor, and the 1- and 2-year survival rates were 27% and 10%, respectively. Survival did not differ in patients with pure SCC or mixed glandular and small cell carcinoma. Higher elevation of pretreatment serum NSE value was associated with the poor prognosis.     

Primary adenocarcinoma of the appendix invading the urinary bladder

We report a case of adenocarcinoma of the appendix invading the urinary bladder in a 75-year-old man. Although cystoscopic examination and computed tomography suggested a primary or secondary bladder tumor, repeated transurethral bladder biopsy could not confirm the neoplasm. At operation a primary neoplasm of the appendix invading the bladder was discovered and en bloc resection of the urinary bladder with the adherent cecum followed by an ileocolonic anastomosis and ureterocutaneostomy was performed. The patient died of carcinoma 13 months later.     

Prostate cancer and the multiple primary malignant neoplasm syndrome

In an attempt to evaluate the relationship of prostate cancer to the multiple primary malignant neoplasm syndrome, 626 prostate cancer cases were reviewed. Patients with one malignant tumor appear to be no more at risk of developing a prostate cancer than individuals who have never had a tumor.     

Two cases of mucinous adenocarcinoma of the prostate]

We report two cases of mucinous adenocarcinoma of the prostate. A 56-year-old man underwent subcapsular prostatectomy under the diagnosis of benign prostatic hyperplasia in 1968, and was found to have mucinous adenocarcinoma of the prostate, which proved to be prostatic acid phosphatase (PAP) and prostate specific antigen (PSA) positive, and carcinoembryonic antigen (CEA) negative by immunohistochemical staining. Subsequently he received 70 Gy of irradiation to the prostate, but died in 1976, when serum PAP was elevated. Autopsy revealed metastases to the liver, lungs, bone, peritoneum, spleen, pancreas, lymph nodes, and no primary gastrointestinal adenocarcinoma. The other case was a 57-year-old man, who underwent transurethral resection (TUR) for papillary tumor located just lateral to the verumontanum in 1982. The tumor was misdiagnosed as adenomatous polyp, and was PSA and PAP negative, and CEA positive. After 3 TURs of the recurrent tumor on the prostatic urethra, he underwent prostatourethrectomy, pelvic lymphadenectomy, and cystostomy for radical cure in 1985. The specimen proved to be mucinous adenocarcinoma of the prostate. He suffered recurrence of the tumor in the retrovesical space in 1987, and died in 1990. Autopsy revealed no evidence of metastasis except the local recurrence and no primary gastrointestinal adenocarcinoma.     

Bladder carcinoma associated with hypercalcemia: report of 3 cases

Three cases of bladder carcinomas associated with hypercalcemia were presented. Case 1: A 43-year-old male was diagnosed as having bladder carcinoma 2 years ago and treated in another hospital by partial cystectomy with uretero-vesiconeostomy of the left side. On March 6, 1985, in our clinic, he received a total cystectomy with an ileal conduit for urinary bladder carcinoma. A 5-month post-operative clinical examination showed recurrence of the carcinoma with elevated serum Ca level (15.6 mg/dl). He was treated with eel-calcitonin, predonine, indomethacin, and furosemide, but died on August 23, 1985. Autopsy disclosed carcinoma of the urinary bladder (transitional cell cancer much greater than squamous cell cancer). Case 2: A 51-year-old male was diagnosed as having transitional carcinoma of the urinary bladder and was treated in our clinic by total cystectomy with cutaneous ureterostomy. Three months after the operation, he was readmitted with complaints of anorexia and disturbances of consciousness. His serum Ca level was elevated (17 mg/dl), and clinical examination showed recurrence of the carcinoma; bone scan revealed no metastasis. He was treated by radiotherapy with eel-calcitonin, predonine, indomethacin, and furosemide, but died on October 22, 1985. Autopsy disclosed carcinoma of the urinary bladder (squamous cell cancer). Case 3: A 72-year-old male was diagnosed as having a large urinary bladder tumor. An IVP showed a left non-functioning kidney. On admission, he complained of anorexia and confusion. His serum Ca level was elevated (13.8 mg/dl); bone scan revealed no metastasis.(ABSTRACT TRUNCATED AT 250 WORDS)     

Metastatic ductal carcinoma of the prostate: a rare variant responding to a common treatment

Ductal carcinoma of the prostate is a rare histologic subtype of prostate carcinoma. It represents 0.4% to 0.8% of all prostate cancers and is associated with a poor prognosis. Given the paucity of cases reported in the literature on ductal prostate carcinoma, little is known about how this cancer responds to cytotoxic chemotherapy. We report the case of a 56-year-old male who presented to our clinic with hemoptysis, cough and hematuria and was found to have metastatic ductal carcinoma of the prostate. He was initiated on docetaxel chemotherapy, which has been previously shown to improve overall survival in patients with metastatic prostate adenocarcinoma, but has never been studied in this less common subtype of prostate cancer. To the best of our knowledge, the following is the first reported case of a patient with metastatic ductal carcinoma of the prostate responding to docetaxel chemotherapy.     

Primary squamous cell carcinoma in the gastric remnant

A 67-year-old male developed primary gastric squamous cell carcinoma (SCC) 13 years after undergoing distal gastrectomy for gastric cancer. Gastroscopy revealed a type 2 gastric remnant tumor and tumor biopsies revealed poorly differentiated carcinoma. The patient underwent remnant gastrectomy with lateral segment hepatectomy, splenectomy, partial resection of diaphragm, and distal partial esophagectomy. The histological findings revealed SCC without an adenocarcinoma component in the gastric remnant tumor. The patient died 13 months after surgery due to multiple-organ metastasis of gastric SCC. The post-operative prognosis of gastric SCC cases tends to poorer than that of gastric adenocarcinoma. Early diagnosis is important to improve the prognosis of primary gastric SCC and pathogenetic analysis of gastric SCC may contribute to improving the diagnosis and treatment of carcinogenesis and the prognosis of gastric SCC.     

Genitourinary small cell carcinoma: a retrospective review of treatment and survival patterns at The Ottawa Hospital Regional Cancer Center

OBJECTIVE: To review patients with genitourinary (GU) small cell carcinoma (SCC) treated at a regional cancer centre, as due to its rarity and aggressive nature, GU SCC remains a therapeutic challenge. PATIENTS AND METHODS: The charts of patients managed at a regional cancer centre between 1991 and 2002 for any GU diagnosis were manually reviewed to identify GU SCC. Demographic, staging, treatment and outcome data were extracted. The Veterans Administration small cell lung cancer staging classification of "limited" or "extensive" disease was adapted for SCC of the prostate and bladder (with "limited" defined as disease localized to the true and false pelvis, and "extensive" as disease beyond the pelvis). RESULTS: In all, 555, 858 and 5066 new cases of primary renal, bladder and prostate cancer, respectively, were identified. Of these patients, 22 had GU SCC (12 bladder and 10 prostate; there were no cases of SCC of the kidney). Eight of 12 patients with bladder SCC had limited disease; five of 12 are alive (all with limited disease at diagnosis), and the median survival was 19.8 months. Surviving patients received similar therapy, with transurethral resection of the bladder tumour, platinum-based chemotherapy, etoposide (4-6 cycles), and radical radiotherapy (56-60 Gy). Two of 10 patients with SCC of the prostate had limited-stage disease, but all 10 died, the median survival being 9.5 months. Survival by stage for both types combined was 59 months for limited disease and 8 months for extensive disease. CONCLUSIONS: These results indicate that GU SCC is an aggressive cancer; limited-stage SCC of the bladder or prostate, when treated with platinum/etoposide chemotherapy and radical radiotherapy, has a more favourable outcome than that of extensive GU SCC.     

Combined small-cell carcinoma/adenocarcinoma of prostate: report of two cases

We report two cases of combined small-cell carcinoma (SCC) and adenocarcinoma of prostate. Case 1 was a 76-year-old man with loss of appetite and body weight and neck lymphadenopathies. Whole body computed tomography (CT) revealed prostatic swelling, pancreatic mass, para-aortic lymphadenopathies, and multiple lung nodules. Elevation of tumor markers (prostate specific antigen [PSA, 1,760 ng/ml] and neuron-specific enolase [NSE, 88 ng/ml]) was noted. Needle biopsy of the prostate demonstrated both SCC and adenocarcinoma. Only within the part of SCC, were neuroendocrine (NE) markers (chromogranin A [CgA], NCAM, and synaptophysin [SNP]) expressed. Maximum androgen blockade (MAB) resulted in a decrease of PSA (5.13 ng/ml) but an increase of NSE (810 ng/ml). Cytotoxic chemotherapy was not possible because of his poor performance state and renal dysfunction. The patient died three months after the diagnosis. Case 2 was a 69-year-old male with dysuria. The symptom and elevated serum PSA (23.1 ng/ml) prompted prostatic needle biopsy, which demonstrated combined SCC/adenocarcinoma. NE markers (CgA and SNP) were weakly expressed in the part of SCC. Serum NSE was 6.9 ng/ml. After MAB, serum PSA dropped to the normal range (0.192 ng/ml) and the effect of MAB was judged as complete response (CR). The patient has been alive for 15 months with no signs of relapse. Treatment of combined SCC and adenocarcinoma of prostate poses a dilemma. In Case 1, MAB was effective for adenocarcinoma but not for SCC. The opposite situation would be expected with systemic chemotherapy. However, the histologically similar Case 2 achieved CR with MAB alone. Much remains to be elucidated to better manage combined SCC/adenocarcinoma of prostate.     

Simultaneous presentation of adenocarcinoma of prostate and transitional cell carcinoma of bladder

Simultaneous presentation of transitional cell carcinoma of the bladder and adenocarcinoma of the prostate is not uncommon. Twenty-two patients were diagnosed as having simultaneous or concurrent presentation of prostate and bladder carcinomas between January 1970 and July 1986. The overall five-year survival was 40 percent, with patients presenting with prostate cancer doing better (50%) than those with bladder cancer (32%). Retrospective review of these cases suggests that primary therapy should be directed to the most advanced cancer. Incidental prostate cancer may be "cured" with a cystoprostatectomy and, when indicated, radiation therapy added postoperatively for the bladder cancer. Eleven patients presented with Stage A prostate cancer: 10 of the 11 were treated for their bladder cancer. Treatment was usually radical cystoprostatectomy with or without postoperative radiation. None died of prostate cancer. Patients presenting with advanced stage prostate cancer have had recurrence or have died of the cancer.     

Tumors of the bladder in renal transplant patients: report of a case of adenocarcinoma and review of known cases.

A case is presented of adenocarcinoma of the bladder in a 36-year-old man who had undergone renal transplantation 4 years previously. Treatment was cystectomy and ileal loop diversion. A review of the known cases of bladder tumors obtained from the literature and from the Human Renal Transplant Registry is discussed. The 8 cases presented include 4 transitional cell carcinomas, 1 squamous cell carcinoma, 1 nephrogenic adenoma and 2 adenocarcinomas. The unusual occurrence of adenocarcinoma in young male subjects is noted.     

Two cases of metastatic renal tumor

Two cases of metastatic renal tumor are reported, one in a 78-year-old male who had undergone total gastrectomy for gastric carcinoma, and the other in a 45-year-old female who had undergone hysterectomy for cervical carcinoma of the uterus. The chief complaint was flank pain and nephrectomy was performed in both cases. Histopathological examination of the removed specimen revealed metastatic renal tumor the primary site of which was probably the stomach in the first case and cervix uteri in the second case. The literature on metastatic renal tumors in Japan is reviewed.
