The case was a 63-year-old male with the chief complaint of hematuria. A local doctor made the diagnosis of a bladder tumor (egg-sized) on the basis of the results of ultrasonography. CT-scan and cystoscopy. He was thus referred to our Department for treatment. Histopathological study of the biopsied tumor specimen revealed that the tumor was a squamous cell carcinoma. The bilateral internal iliac arteries were occluded for 48 hours, and 100 mg of CDDP and 40 mg of
THP
were arterially infused. After 7 days, hematuria disappeared, as did the tumor 5 weeks after treatment. No malignancy was noted from histological examination of a biopsy specimen obtained from the cured cancer region using a cystoscope. Since then, there was no recurrence for 12 months. Thus, this approach is thought to be an effective treatment for primary
bladder cancer
.

Intravesical instillation of pirarubicin (
THP
) was performed on 66 patients with superficial
bladder cancer
after transurethral resection to evaluate the prophylactic effect against tumor recurrence. Intravesical chemotherapy was carried out at the concentration of 20mg/40ml.
THP
was initially instilled three times for one week, following instillation of every two weeks for ten times, and then every one month for seven times. Bladder irritability was demonstrated 21 of 66 cases (31.8%). Although there was a case of contracted bladder, generalized side effect was no case. Eligible cases for evaluation of efficacy were 43 out of 66 patients. The non-recurrence rate (by Kaplan-Meier's method) at one and two years were 90.4% and 77.8%, respectively. Intravesical
THP
instillation seems to be effective for the purpose of prophylaxis against the recurrence of superficial bladder tumor.

From January, 1987 through January, 1990, partial cystectomy was performed for 4 (18%) of 22 patients with invasive
bladder cancer
who had received neoadjuvant intra-arterial chemotherapy. The criteria of patient selection for partial cystectomy were: 1) invasive
bladder cancer
showing good response (greater than or equal to PR) to neoadjuvant chemotherapy, 2) solitary or localized tumor that can be eradicated by segmental resection, and 3) tumor of stage T3 or less. As a rule, cisplatinum (100 mg/m2) and
THP
-adriamycin (40 mg/m2) were administered selectively to the internal iliac artery by one-shot infusion. Concurrently, sodium thiosulfate (10 g/m2), a neutralizing agent against cisplatinum, was administered intravenously. All four patients had achieved clinical complete responses by one or two courses of intra-arterial chemotherapy, and then underwent partial cystectomy with pelvic lymphadenectomy. Pathological examination revealed pTONO in two patients, and the remains were pT3aNO and pT3bN1. After the mean follow-up of 24 months, three of them are alive with no evidence of disease, and also with normal bladder and sexual functions. However, one with pT3bN1 tumor underwent total cystectomy 5 months later for local recurrence (pT4b) and had died of cancer 18 months later. Neoadjuvant intra-arterial chemotherapy followed by partial cystectomy should be the most applicable conservative therapy with high radicality for invasive
bladder cancer
, when: 1) the patient has localized invasive cancer showing good response (greater than or equal to PR) to neoadjuvant chemotherapy, 2) the tumor is stage T3a or less and without findings of tentacular invasion (INF gamma) by pre-operative biopsy, and 3) pre-operative multiple biopsy is performed as deeply as possible along the prearranged incision line.

Focused high-energy shock waves (6,000 to 10,000 shots) were targeted under ultrasound guidance onto implanted
urinary bladder cancer
in rabbits to elucidate its effect. Although only focal necrosis of the tumor was seen following 6,000 to 10,000 shots daily for 3 days or following chemotherapy (
THP
-adriamycin) alone, almost total tumor necrosis was observed following a combined shock-wave therapy for one day and
THP
-adriamycin administration, demonstrating an additive and/or synergetic effect on rabbit
urinary bladder cancer
.

In the urological field, one of the most effective drugs is doxorubicin. A cooperative phase II study on pirarubicin (
THP
), a new anthracycline with less cardiotoxicity than doxorubicin, was performed in 14 institutions for treating urological tumors.
THP
was administered intravenously 3 or more times (as one course, 30-40 mg/m2 once a week, every 3 weeks or 20 mg/m2 2 consecutive days a week every 3 weeks). Fifty-four of the 63 patients included in this study were evaluable. An overall efficacy rate was 18.5% (10/54), consisting of transitional cell carcinoma 24.3% (9/37;
bladder cancer
6/27 (22.2%), tumors of the renal pelvis and ureter 3/10 (30.0%), and prostatic cancer 1/15 (6.7%). Adverse effects were mostly slight especially alopecia (15.9%, WHO grade 1:7 patients and grade 2:3 patients), and there was no problem attributable to cardiotoxicity of
THP
. Leukocytopenia was seen for 65.1% (grade 1:14 patients, grade 2:13 patients, grade 3:13 patients, and grade 4:1 patients). The nadir was observed about 2 weeks later and it took about 2 weeks for the recovery. Thus, it can be concluded that the usefulness of
THP
in treating urological tumors is comparable to or better than that reported for doxorubicin. Based on the above results, a combination regimen including
THP
has been investigated in Japan.

Eight-MHz radiofrequency hyperthermia (H) using Thermotron-RF8, and its combination with irradiation (RH), anticancer drugs (CH) or anticancer drugs plus irradiation (CRH), were carried out for a total of 93 urological malignancies: 19 cases of renal cancer, 3 of renal pelvic cancer, 4 of ureteral cancer 39 of
bladder cancer
, 8 of prostatic cancer, 14 of metastatic lesion of urological cancers and 6 of other urological cancers. All had failed in previous treatments, or had not undergone surgery because of their poor general condition. Nine cases, including 1 of renal cancer, 1 of ureteral cancer, 4 of
bladder cancer
, 2 of prostatic cancer and 1 of metastatic lesion of
bladder cancer
, were treated with (H). Fifty cases, including 4 renal cancer cases, 20
bladder cancer
cases and 6 prostatic cancer cases, were treated with (RH). Eight of the 19 cases of renal cancer were treated with mitomycin C-microcapsule (MMC-mc) embolization prior to radiohyperthermia (CRH). The remaining 6 cases of renal cancer received embolization with MMC-mc followed by RE-heating (CH). Eighteen of the 48 cases of urothelial cancer or its metastasis, including 1 of renal pelvic cancer, 15 of bladder a cancer and 2 of metastatic lesion of bladder, received a combined treatment of intravenous
THP
-adriamycin, one of the derivatives of adriamycin and RE-heating (CH). In the remaining 2 cases, one received (CH), and the other received (CRH). Hyperthermia was given twice a week for a total of 10 sessions in 5 weeks. Intratumoral temperature was kept above 42.5 degrees C for 30 to 40 minutes during a one-hour heating. Complete tumor regression was obtained in 9
bladder cancer
cases. Partial tumor regression, defined as a regression of 50% or more, was obtained in 17 cases. A pain relief was attained in 18 of 23 patients with intractable pain due to local tumor infiltration. As side effects, mild skin burns were observed in 21 cases. Ten obese cases, having subcutaneous tissue 15mm thick or more, developed fat tissue induration after treatment.

Eight-MHz radiofrequency hyperthermia (H) using a Thermotron-RF Model 8, and its combination with irradiation (RH), anticancer drugs (CH) or anticancer drugs plus irradiation (CRH), were carried out for a total of 48 urological malignancies: 10 cases of renal cancer, 1 of renal pelvic cancer, 2 of ureteral cancer, 19 of
bladder cancer
, 5 of prostatic cancer, 9 of metastatic lesion of urological cancers and 2 of other urological cancers. All had failed in previous treatments, or had not undergone surgery because of their poor general condition. Four cases, including 2 of
bladder cancer
, 1 of prostatic cancer and 1 of metastatic lesion of
bladder cancer
, were treated with H. Twenty-five cases, including 3 renal cancer cases, were treated with RH. Seven of the 10 cases of renal cancer were treated with mitomycin C-microcapsule embolization prior to RH (CRH). Twelve of the 23 cases with urothelial cancer or its metastasis, including 1 of renal pelvic cancer, 10 of
bladder cancer
and 1 of metastatic lesion of
bladder cancer
, received combined treatment of
THP
-adriamycin, one of the derivatives of adriamycin, by i.v. and RF-heating (CH). Hyperthermia was given twice a week, totalling 10 sessions in 5 weeks. Intratumoral temperature was kept above 42.5 degrees C for 30 to 40 minutes during one-hour heating. Complete tumor disappearance was obtained in the 5
bladder cancer
cases. Partial tumor regression, defined as a regression of 50% or more, was obtained in 11 cases. As side effects, mild skin burns and anorexia were observed in approximately 30 to 40% of cases. Seven obese cases, who had subcutaneous tissue 15 mm thick or more, developed fat tissue induration after treatment.

The effect in combination therapy of high energy under water shock waves (HESW) and anticancer drugs for subcutaneous murine
bladder cancer
(MBT-2) in C3H/He mice was examined. HESW were generated by piezoceramics and directed to the subcutaneous tumor under ultrasonographic guidance. The subcutaneous tumor was exposed to HESW alone (100 MPa, 1000 shots, 3 shots/sec) or in combination with pirarubicin (
THP
, 5 mg/kg, i.p.) or carboplatin (CBDCA, 40 mg/kg, i.p.). Remarkable bleeding in the tumor was seen immediately after the exposure of HESW, destroyed cancer cells appeared after one day and wider and clearly bordered tumor necrosis was observed after three days. In the HESW alone therapy, tumor growth of smaller tumors (< 10 mm3, n = 8) were suppressed more than that of larger tumors (10-35 mm3, n = 11). Tumor growth ratio on the 14th day (TGR 14) (tumor volume on the 14th day/tumor volume on the 1st day) was examined in larger tumors. TGR 14 were 152.2 +/- 146.6 (mean +/- S.D.) in the control (n = 20), 116.3 +/- 98.9 in HESW alone (n = 11), 75.5 +/- 110.7 in
THP
alone (n = 8), 90.7 +/- 61.6 in CBDCA alone (n = 6), 75.8 +/- 72.2 in
THP
+ HESW (n = 9), 3.2 +/- 4.5 in CBDCA + HESW (n = 8) and 0.8 +/- 1.3 in CBDCA + HESW 2 cycles (n = 9). Evident suppression on tumor growth was more often seen in CBDCA + HESW and CBDCA + HESW 2 cycles therapies than in the other therapies (p < 0.01). The cumulative survival rates were higher in CBDCA + HESW and CBDCA + HESW 2 cycles therapies than in the other therapies (p < 0.05). Tumor metastasis was seen only in the lungs of the dead mice after 19 days. Lung metastases were seen in 1/6 in the control, 0/5 in HESW alone, 1/5 in CBDCA alone, 0/6 in CBDCA + HESW and 1/5 in CBDCA + HESW 2 cycles therapy, respectively.

The patient was a 70-year-old male with invasive
bladder cancer
. We performed intermittent arterial infusion (ITI) combined with alteration of blood flow in the bladder wall using the contralateral arterial embolization. As for anti-tumor agents, cisplatin (CDDP) 10mg and pirarubic in (
THP
) 10 mg were selected, and were injected every week for 11 times. Complete response (CR) was noted by cystoscopy and biopsied specimen. In our conclusion. ITI was useful for the treatment of
bladder cancer
.

To establish a method for reasonable clinical use of adriamycin (ADM) and pirarubicin (
THP
) in the intravesical chemotherapy for superficial
bladder cancer
, intracellular concentrations of these drugs were examined in culture cell lines (T-24, T-24/ADM and FHS736b1) with variable durations of contamination. The intracellular concentration of
THP
showed a plateau at 15-30 min. contamination in T-24, and in T-24/ADM, and showed the time dependence of contamination in FHS736b1, human normal bladder mucosa cell line. The intracellular concentration of ADM showed the time dependence of contamination in T-24, T-24/ADM and FHS736b1. And these concentrations of
THP
were 20 times higher than those of ADM. In conclusion, it seems better that
THP
was retained for 5-15 min. in the bladder in the intravesical chemotherapy, from the point of view of drug efficacy and preventing side effects. And it seems good that ADM was retained for more than 30 min. in the case with drug sensitive tumors.
