Magnetic resonance imaging combined with artificial erection for local staging of penile cancer.

OBJECTIVES: To assess magnetic resonance imaging (MRI) combined with artificial erection for local staging of penile cancer. METHODS: We compared local clinical, MRI plus artificial erection, and pathologic staging in 9 cases of penile cancer. Erection was obtained by injecting 10 microg prostaglandin E1 into the corpora cavernosa. T1-weighted and T2-weighted MRI with and without contrast was obtained using a phased array coil. Local treatment was based on tumor location and extent, as defined by the clinical and MRI findings. RESULTS: The histologic diagnosis was squamous cell carcinoma in 8 patients and sarcoma in 1. The MRI and pathologic staging coincided in 8 of 9 patients. MRI, clinical, and pathologic staging coincided in 5 patients: 4 had Stage T2 and 1 had Stage T1 disease. In 2 patients, the MRI and pathologic stage was T2, but the clinical stage differed. Another patient had Stage T2 clinically but T3 by MRI and pathologic staging. In the last patient, none of the stages coincided (clinical Stage T1, MRI Stage T0, and pathologic Stage Tis). The only complication during the procedure was that 1 patient developed priapism after prostaglandin injection, which was relieved by evacuation of the corpora cavernosa. CONCLUSIONS: To our knowledge, this is the first study to use artificial erection with MRI to stage local penile cancer. The method appears promising for local staging of penile cancer, but additional studies are necessary to confirm its utility.

Generation of species cross-reactive aptamers using "toggle" SELEX.

Species cross-reactivity facilitates the preclinical evaluation of potentially therapeutic molecules in animal models. Here we describe an in vitro selection strategy in which RNA ligands (aptamers) that bind both human and porcine thrombin were selected by "toggling" the protein target between human and porcine thrombin during alternating rounds of selection. The "toggle" selection process yielded a family of aptamers, all of which bound both human and porcine thrombin with high affinity. Toggle-25, a characteristic member, inhibited two of thrombin's most important functions: plasma clot formation and platelet activation. If appropriate targets are available, the toggle strategy is a simple measure that promotes cross-reactivity and may be generalizable to related proteins of the same species as well as to other combinatorial library screening strategies. This strategy should facilitate the isolation of ligands with needed properties for gene therapy and other therapeutic and diagnostic applications.

Paradoxical stimulation of prolactin secretion by L-dopa in metastatic prostate cancer and its possible role in prostate-cancer-related hyperprolactinemia.

OBJECTIVE: In addition to sex steroids, prolactin (PRL) may also stimulate prostate cancer growth. Abnormally high blood levels of PRL have been noted in metastatic prostate cancer patients. However, most studies have been limited to the evaluation of basal levels of PRL rather than to investigate its secretion in response to classical endocrine dynamic tests. This study was carried out to analyze PRL secretion in metastatic prostate cancer patients both at basal conditions and in response to L-Dopa and metoclopramide, which represents the most classical inhibitory and stimulatory tests for PRL secretion, respectively. METHODS: The study included 12 patients with metastatic prostate cancer. On separate occasions, PRL secretion was evaluated in response to L-Dopa (500 mg orally) and to metoclopramide (10 mg i.v. as a bolus). Serum levels of PRL were measured by RIA. RESULTS: Mean PRL concentrations significantly increased after metoclopramide administration, even though no PRL response occurred in 6 of 12 patients. L-Dopa was unable to reduce PRL levels, which, in contrast, paradoxically significantly increased in response to L-Dopa, with mean values comparable to those achieved after metoclopramide injection. CONCLUSION: By showing a paradoxical stimulatory effect of L-Dopa on PRL secretion and a lack of response to metoclopramide in some patients, this study would suggest the existence of evident alterations in the neuroendocrine regulation of PRL release in advanced prostate cancer.

Reversal of clinical resistance to LHRH analogue in metastatic prostate cancer by the pineal hormone melatonin: efficacy of LHRH analogue plus melatonin in patients progressing on LHRH analogue alone.

OBJECTIVE: Experimental and preliminary clinical studies have suggested that the pineal hormone melatonin (MLT) may stimulate hormone receptor expression on both normal and cancer cells. Moreover, MLT has appeared to inhibit the growth of some cancer cell lines, including prostate cancer, either by exerting a direct cytostatic action, or by decreasing the endogenous production of some tumor growth factors, such as prolactin (PRL) and insulin-like growth factor-1 (IGF-1). On this basis, a study was carried out to evaluate the clinical efficacy of a neuroendocrine combination consisting of the LHRH analogue triptorelin plus MLT in metastatic prostate cancer progressing on triptorelin alone. MATERIAL AND METHODS: The study including 14 consecutive metastatic prostate cancer patients with poor clinical conditions (median age: 70.5 years; median PS: 50%), refractory or resistant to a previous therapy with the LHRH analogue triptorelin alone. Triptorelin was injected i.m. at 3.75 mg every 28 days, and MLT was given orally at 20 mg/day in the evening every day until progression, starting 7 days prior to triptorelin. RESULTS AND CONCLUSIONS: A decrease in PSA serum levels greater than 50% was obtained in 8/14 (57%) patients. Moreover, PSA mean concentrations significantly decreased on therapy of triptorelin plus MLT. In addition, a normalization of platelet number was obtained in 3/5 patients with persistent thrombocytopenia prior to study. Mean serum levels of both PRL and IGF-1 significantly decreased on therapy. Finally, a survival longer than 1 year was achieved in 9/14 (64%) patients. This preliminary study would suggest that the concomitant administration of the pineal hormone MLT may overcome the clinical resistance to LHRH analogues and improve the clinical conditions in metastatic prostatic cancer patients.

[Clinical response and survival in metastatic renal carcinoma during subcutaneous administration of interleukin-2 alone. Subcutaneous Il-2 in renal carcinoma].

Several clinical studies have demonstrated the efficacy of subcutaneous immunotherapy with Il-2 alone in metastatic renal cell carcinoma (RCC). In an attempt to better define the clinical parameters which may predict the efficacy of treatment, the present study shows the results obtained with subcutaneous Il-2 alone in 91 evaluable metastatic RCC patients. IL-2 was injected subcutaneously at 3 million IU twice/day for 5 days/week for 6 weeks, corresponding to one immunotherapeutic cycle. In nonprogressing patients, a second cycle was given after 28-day rest period. A complete response (CR) was achieved in 2/91 patients. Moreover, 19/91 patients had a partial response (PR). Therefore, objective response (OR) rate was 21/91 (23%) patients. Stable disease (SD) was achieved in 41 patients, while the remaining 29 patients had a progressive disease (PD). OR rate was significantly higher in patients with a long disease-free survival than in patients with synchronous metastases, in nephrectomized patients than in the non-nephrectomized ones, and in patients with high than in those with low PS. The survival obtained in patients with CR or PA was significantly longer with respect to that found in patients with SD or PD. The toxicity was substantially low in all patients. This study confirms that the subcutaneous immunotherapy with IL-2 alone is an effective and well tolerated therapy of metastatic RCC.

[Preoperative subcutaneous immunotherapy with interleukin-2 in renal carcinoma with synchronous metastasis: randomized clinico-biological study. Preoperative use of Il-2 in renal carcinoma].

Despite the efficacy of IL-2 in the treatment of metastatic renal cell carcinoma (RCC), the prognosis of patients with synchronous metastases still remains poor. Nephrectomy itself, as well as other surgical operations, may further suppress the antitumor immune response. Previous studies suggested that the preoperative injection of IL-2 may neutralize surgery-induced lymphocytopenia in advanced colon cancer. On this basis, a pilot randomized study was performed in an attempt to evaluate the effects of a preoperative administration of IL-2 on postoperative lymphocyte numbers and on the survival in advanced RVV patients with more than 3 synchronous metastases. The study included 20 consecutive patients, who were randomized to receive nephrectomy alone or nephrectomy plus preoperative subcutaneous immunotherapy with IL-2 (18 million IU/day for 3 days). Then, all patients underwent postoperative immunotherapy with IL-2 (6 million IU/day for 5 days/week for 6 weeks). Surgery-induced lymphocytopenia was completely abolished by IL-2 preoperative injection. The frequency of postoperative complications was significantly higher in controls than in patients preoperatively treated with IL-2. On the contrary, significant differences between control and patients preoperatively treated with IL-2 were observed neither in the clinical response to IL-2 immunotherapy, nor in the percent of 1-year survival. The results of this preliminary pilot study would suggest that IL-2 preoperative immunotherapy may neutralize surgery-induced lymphocytopenia and reduce the postoperative complications in RCC patients with synchronous metastases, without, however, influencing their prognosis in terms of survival time.

[Immunotherapy for metastatic renal carcinoma with interleukin-2 in a subcutanous administration schedule of short duration. Subcutaneous IL-2 in renal carcinoma].

It has been shown that low-dose subcutaneous (SC)IL-2 exerts an efficacy similar to that described for the intravenous high-doses in the immunotherapy of metastatic renal cell cancer (RCC). However, it remains to be established which could be the optimal duration of treatment. The most common schedules with subcutaneous IL-2 are generally consisting of 6 weeks of therapy, with an IL-2 dose of about 6 million IU/day. This study was performed to evaluate the efficacy of IL-2 subcutaneous immunotherapy with a duration of 4 weeks only. The study included 13 evaluable metastatic RCC patients. IL-2 has been injected subcutaneously at 6 million IU/day for 6 days/week for 4 weeks, by repeating a second cycle in nonprogressing patients after a 21-day rest period. Objective tumor regressions were achieved in 3/13 (23%) patients consisting of CR in 1 and PR in the other 2. Stable disease was obtained in other 6 patients. This preliminary study would suggest that a shorter dose-matched S.C.IL-2 immunotherapy may have a similar therapeutic efficacy in metastatic RCC. Therefore, the 4-week IL-2 S.C. immunotherapy, instead of the 6-week schedule could become the standard immunotherapeutic schedule, with following decreased cost and toxicity.

[Orthotopic ileal neobladders in men and women: techniques and comparison].

PURPOSE: evaluation of results and complications of ileal orthotopic neobladders in men and women with transitional cell carcinoma. MATERIALS AND METHODS: between 12-89 and 12-95 we performed 146 radical cystectomy for bladder neoplasm, in 32 patients we can perform ileal orthotopic neobladder, 29 were male and 3 were female. Oncologic indications to this kind of operation were: clinical stage T2, T3a, T3b, T1G3 multicentric and or recurrence, absence of metastasis absence of nodal metastasis, negativity of urethral biopsy. General contraindications were urethral stenosis and incontinence. Oncological contraindications, in woman, were bladder neck neoplasm or urethral neoplasm. In 4 patients we use Camey II technique, in 19 pts we performed the paduan ileal neobladder, in 9 pts we use Hautmann technique. 7 patients performed neoadjuvant chemotherapy with 4 circles of MVAC, 4 pts underwent adjuvant chemotherapy, and 2 pts salvage chemotherapy. In woman we take care during cystectomy to dissect cardinal ligament very close to cervix uteri, to resect the uterosacral ligament far to the sacrum. We did not dissect under the ureter and we cut the urethra 0.5-1 cm far from the bladder neck. RESULTS: follow up was between 6 and 66 months. 24 patients are now alive and disease free, 2 patients are alive with disease progression, 1 have a pelvic recurrence and 1 have pulmonary recurrence. 4 pts died for disease progression and 2 for non oncological cause, quality of life was considered as regard to continence and sexual activity. 1 pts was completely incontinent and 1 pts has nocturnal incontinence with a daily micturation every 1 hour. We can evaluate only 18 patients for sexual activity and 4 reported normal erection. COMPLICATIONS: in three cases we had to reoperate for early complications due to mechanical bowel obstruction, ileocutaneous fistula and wound dehiscence. In three cases we had the formation of stones, in two patients ureteroileal stenosis, in two cases urethro-ileal stenosis and 1 reflux from the neobladder. Orthotopic ileal neobladder allows a very good quality of life and is the first choice derivation after radical cystectomy.

[Lymphocyte levels before treatment with subcutaneous interleukin-2 and during maintenance treatment in relation to the clinical efficacy in metastatic renal carcinoma].

AIMS AND BACKGROUND: the antitumor activity of IL-2 is mediated by an increase in lymphocyte number. Moreover, our previous studies have shown that therapy for 1 week/month with low-dose subcutaneous IL-2 is sufficient to maintain high levels of lymphocytes in cancer patients who have had tumor regression or stable disease (SD) in response to IL-2 immunotherapeutic cycles. This study was performed to establish whether tumor progression in cancer patients chronically treated with IL-2 may be associated with lymphocyte number decline. METHODS: the study included 60 metastatic renal cell patients, who were treated with 2 induction cycles of IL-2 subcutaneous immunotherapy (6 million IU/day for 5 days/week for 6 weeks, corresponding to one cycle). Tumor regression occurred in 17/60 patients, 23 patients a SD, and the remaining 20 cases progressed. Non-progressed patients (n = 40) underwent a maintenance therapy consisting of one week of therapy every month. After a median follow-up of 18 months, 29/40 patients with response or SD had progressed. The immune investigation consisted of lymphocyte, T lymphocytes, NK cell number determination and sCD25 level detection. RESULTS: the mean number of lymphocytes, T lymphocytes and NK cells observed on IL-2 maintenance therapy was significantly higher than that seen before beginning the immunotherapy. Moreover, mean number of lymphocytes and mean levels of sCD25 observed at the time of tumor progression were respectively lower and higher than those seen on maintenance therapy in the same patients, without, however, significant differences. CONCLUSION: despite the importance of lymphocytes in mediating the antitumor activity of IL-2, this study shows that tumor progression in cancer patients chronically treated with low-dose IL-2 after response or SD during IL-2 induction cycles is not associated with a significant decline in lymphocyte, T lymphocyte or NK cell numbers. Further studies, carried out to analyze the functional status of immune cells at the time of tumor progression, will be necessary to define the role of immunity in cancer patients progressing under IL-2 chronic therapy.

[Prognostic predictive factors of the clinical response to immunotherapy with subcutaneous interleukin-2, in patients with metastatic renal carcinoma: analysis of 60 cases].

The intravenous immunotherapy with high-dose interleukin-2 (IL-2) would constitute one of the most effective treatments of metastatic renal cell carcinoma (RCC). More recently, IL-2 subcutaneous therapy has also appeared active, either alone or in association with interferon, with results comparable to those found with the intravenous route of injection, but with a lower toxicity. On this basis, we have designed a protocol of treatment with low-dose IL-2 alone given subcutaneously as a first or a second line therapy in metastatic RCC. The study included 60 consecutive patients (pts) (M/F: 39/21, median age 56 years, range 26/74). IL-2 was given at a dose of 3 millions IU twice/day for 5 days/week, for 6 weeks, corresponding to one cycle. In non progressed pts a second cycle was repeated after a 28-day rest period. Dominant metastasis sites were, as follows: soft tissues: 8; bone: 11; lung: 29; liver: 3; liver plus lung: 7; adrenal: 2. The minimum follow-up was 18 months and the median follow-up was 34 months (range 18-48). A complete response (CR) was achieved in 2/60 (3%) pts. A partial response (PR) was obtained in 15/60 (25%). Therefore, tumor objective rate (CR + PR) was 17/60 (28%). The median duration of response was 13 months (4-33).(ABSTRACT TRUNCATED AT 250 WORDS)

A randomized study of low-dose interleukin-2 subcutaneous immunotherapy versus interleukin-2 plus interferon-alpha as first line therapy for metastatic renal cell carcinoma.

AIMS AND BACKGROUND: IL-2 given subcutaneously in combination with interferon-alpha 2b (IFN) appears to induce a response rate comparable to that obtained with IL-2 intravenous injection in patients with metastatic renal cell carcinoma (RCC) but with lower toxicity. The role of IFN when combined with IL-2 has however still to be defined. The present study was performed to draw some preliminary conclusions about the effect of IFN in combination with IL-2 in metastatic RCC. METHODS: The study included 30 consecutive patients with metastatic RCC who were randomized to treatment with IL-2 subcutaneous therapy (3 million IU twice/daily for 5 days/week for 6 weeks) or with IL-2 plus IFN (5 million U/m2 subcutaneously thrice weekly). In patients without progressive disease, a second cycle was repeated after a 28-day rest period. RESULTS: No significant difference in partial response rate was found between patients treated with IL-2 alone and those given IL-2 plus IFN (5/15 vs 4/15). Similarly, no difference was seen in the percentage of stable disease (7/15 vs 7/15). Toxicity was higher in patients who received IL-2 plus IFN. Lymphocyte and eosinophil mean increase was higher in patients treated with IL-2 alone than in those treated with IL-2 plus IFN, without however any significant difference. CONCLUSIONS: The present results, which require confirmation in a larger series, indicate that combination with IFN does not increase the efficacy of IL-2 subcutaneous immunotherapy in metastatic RCC but only the toxicity of treatment.

[Immunotherapy with low-dose subcutaneous interleukin-2 in metastatic renal carcinoma].

The intravenous injection of interleukin-2 (IL-2) has appeared to induce tumor regression in metastatic renal cell carcinoma (RCC). IL-2 given subcutaneously has also appeared to be effective when it is administered in association with interferon-alpha (INF), but with a lower toxicity in comparison to the intravenous route of administration. The present study was carried out to evaluate the efficacy of a subcutaneous immunotherapy with IL-2 alone in metastatic RCC. The study included 30 consecutive patients affected by metastatic RCC, 14 of whom had been pretreated with INF plus vinblastine, while the other 16 patients received IL-2 as a first line therapy of their metastatic disease. IL-2 was given subcutaneously at a dose of 3 million IU twice/day for 5 days/week for 6 consecutive weeks, corresponding to one cycle of immunotherapy. No complete response was obtained. A partial response (PR) was achieved in 10/30 (33%) patients (median duration: 7 months, range 5-25), without any significant difference between patients pretreated with IFN and nonpretreated patients (4/14 vs 6/16). Response rate was significantly higher in nephrectomized patients than in those who did not undergo nephrectomy (10/25 vs 0/5; P < 0.01). Moreover, response rate was significantly higher in patients with performance status (PS) greater than 40% than in those with PS lower than 40% (10/23 vs 0/7; P < 0.01). A stable disease (SD) was obtained in 12/30 (40%) patients (median duration 5 months, range 3-13), while the remaining 8/30 (27%) progressed. The increase in lymphocyte and eosinophil mean number was significantly higher in patients with PR or SD than in the progressed ones.(ABSTRACT TRUNCATED AT 250 WORDS)

[Neoadjuvant chemotherapy using cisplatin (CDDP) and methotrexate (MTX) in carcinoma of the bladder].

From June 1986 to November 1989, 7 patients (pts.) with transitional bladder cancer were treated with CDDP 70 mg/m2 i.v. on day 1 and MTX 40 mg/m2 i.v. on days 8 and 15. The initial stage was T2 N0 M0 (2), T2 N0 M0 (8), T4 N0 M0 (4) and T3-4 N+ M0 (3). The median age was 56 years. After a median number of two cycles (1-5) of CDDP-MTX, 3/17 pts. (17.6%) had a complete remission (CM), 9/17 pts. (53%) a partial response (PR) greater than 50%, 4/17 pts. (23.4%) a PR less than 50%, 1/17 pts. (6%) a stable disease. Nausea and vomiting occurred in almost all pts., 20% of pts. had grade 3 stomatitis, 35% of pts. had diarrhoea, 20% of pts. had conjunctivitis, 7% of pts. had a bone marrow depression and hair loss. One patient had severe renal and liver toxicity and grade 4 bone marrow suppression with sepsis, completely controlled after intensive care. The treatment after neoadjuvant chemotherapy was: radical cystectomy (11)- in one following radiotherapy -; partial resection + lymphoadenectomy (2); TUR (4) in 1 pt. with lymphoadenectomy. After a median follow-up of 28 months (6-36), 12/17, equivalent to 71% of pts. are disease free, 3/17 (17%) are alive with disease, 2/17 (12%) died. In conclusion the association of neoadjuvant CDDP-MTX can induce a high percentage of response, and can preserve bladder function in some patients. Further controlled trials and a longer follow-up are needed to better define the exact role of this combination in terms of disease free survival, total survival and quality of life.

[A new classification of reno-ureteral lithiasis].

The Authors suggest a change in their surgical classification of renal calculi to conform the description to the new techniques in the treatment of renal calculosis. Category "C" describes the morphology and topography of renal stones in five degrees (C1-C5); small letters "p, s, m, i" indicate the pelvis, superior, middle, inferior calyces; "n" and "a" symbolize stone having a size similar to or exceeding normal shaped renal cavities. "Cu" indicates ureteral calculi; small letters "l, i, p" indicate lumbar, iliac, pelvic ureteral stones. "N" describes the nature of the calculi. Category "E" stands for the excretory tract; "+" and "-" indicate the presence or absence of dilatation, the small letters "e, i" show the extra or intrarenal position of renal cavities; "no" and "o" indicate absence or presence of intrinsic obstruction of the excretory tract. "R" points out the number of surgical recurrences. Category "P" indicates the function of the parenchyma; numbers 1, 2, 3, refer to normal renal function, moderate or serious insufficiency. "U" stands for unique functional or anatomical kidney; "I" indicates the presence of infection.

[Prognostic parameters in extracorporeal lithotripsy].

Extracorporeal lithotripsy consists of applying shock waves (electrohydraulic and piezoelectric) from outside the human body, which pass through the body tissues without damaging them breaking down the urinary calculi into particles which can then be automatically expulsed through the excretory tract. The object of this study is to analysis some of the important parameters which affect the success of the extracorporeal lithotripsy. These factors are as follows: 1) type of shock wave: electrohydraulic or piezoelectric, their action mechanism, methods of fragmenting the urolites; 2) the chemical composition of the calculi and its consequential resistance to the fragmented shock waves; 3) Patency, tone and peristalsis of the intra and extrarenal excretory tract for expulsing the urolite particles; 4) general conditions of the urinary apparatus. From the interaction of these 4 variables arise different clinical situations which must be evaluated before operating in order to develop the proper therapeutic subscription for a renal-urethral lithiasis. The current therapeutic procedures for renal-urethral lithiasis are as follows: electrohydraulic and piezoelectric extracorporeal lithotripsy; electrohydraulic waves or ultrasound percutaneous litholapaxy; operative urethroscope; traditional surgery; chemolysis.

[Results of calcitonin therapy of the painful symptoms caused by osteolytic metastases of prostatic carcinoma].

Albeit within the limits imposed on us by the restricted number of cases, we can state that--in the present state of research--calcitonin constitutes a useful complement in treatment of osteolytic metastasis induced by carcinoma of the prostate. Is utilisation is justified by the effects observed: on the one hand, osteogenesis as a factor protecting against the aggressivity of the tumoural cells, and on the other the considerable antalgic strength allied with improvement in the calcium, phosphorus and phosphatase values. For some time we have replaced pig calcitonin with salmon calcitonin: the comparative results with this second product will be the subject of a subsequent paper.
