Skin metastases from transitional cell carcinoma are quite rare. The present case report describes the results of a combination of mitomycin C and lonidamine administered as third-line chemotherapy in a patient with pulmonary and skin involvement from bladder cancer. The partial response obtained suggests that further testing should be carried out on the activity of this association in a second-line approach.
The demonstrated association with hematologic neoplasms may partially account for the poor survival of patients with mediastinal nonseminomatous germ cell tumors (MNSGCT) compared to patients with testicular and retroperitoneal counterparts. It has been shown that the median interval from the diagnosis of MNSGCT to the diagnosis of the hematologic disorders is 6 months, which contrasts sharply with the average time of 2 to 3 years for the development of therapy-related leukemias. The 2 cases herein described, 1 male and 1 female, developed acute M2 leukemia 4 and 2 years after the diagnosis of MNSGCT. In the second patient (the first female ever described), we cannot exclude a pathogenetic role of the PEB regimen (platinum, etoposide, bleomicin), even though the total dose of etoposide administered has been demonstrated to have a mild leukemogenic potential. This is not the case of the first patient, who did not receive adjuvant chemotherapy after the radical resection of primary MNGSCT and developed the hematologic disorder a few months after local recurrence. In conclusion, the time elapsed from chemotherapy administration does not discriminate the hematologic neoplasms associated to MNGSCT from those related to therapy.
In a prospective trial conducted by the Gruppo Onco Urologico Piemontese, newly diagnosed prostate cancer patients with bone metastases were randomized to receive goserelin (3.6 mg subcutaneously every 4 weeks) or goserelin plus mitomycin at 14 mg/m2 i.v. every 6 weeks. Treatment was planned to be continued until progression. The study was interrupted because of inadequate accrual rate when 63 patients had been recruited. A long-term follow-up (median, 47 months), performed to counterbalance the limited number of patients included, revealed no difference in time to progression and overall survival between the study treatments. However, 56.5% of assessable patients allocated to the chemotherapy arm presented a > or =90% reduction of prostate-specific antigen levels compared with 36.3% in the goserelin group, and previously elevated levels normalized in 73.9% versus 45.4%. Non-progressing patients received 5-7 cycles of mitomycin C with acceptable toxicity, but the cytotoxic treatment was interrupted early in all cases within the first year due to cumulative myelotoxicity. In conclusion, the results, although inconclusive, fail to support a clear advantage in terms of cost/benefit of chemotherapy plus hormone therapy over hormone treatment alone in advanced prostate cancer with bone involvement.
The Italian Group on Rare Tumors undertook a phase II study of a combination of epirubicin and interleukin-2 in 21 chemotherapy-naive patients with malignant mesothelioma. All patients had bidimensionally measurable disease at CT scan. Treatment included Intravenous administration of epirubicin at a dose of 110 mg/m2 i.v. on day 1, and interleukin-2 at a dose of 9 MU subcutaneously from day 8 to day 12 and from day 15 to day 19. Cycles were repeated every three weeks, up to six times in the absence of progressive disease. Treatment response was evaluated after two cycles of therapy. Only one patient achieved a partial response, resulting in an overall response rate of 5% (1/21) with a median progression-free and overall survival of 5 and 10 months, respectively. Toxicity was relevant and caused treatment discontinuation in many patients. These results do not support the use of such a combination in the management of malignant mesothelioma.
Several methods for analyzing CgA using either monoclonal or polyclonal antibodies have been developed, which differ in their diagnostic performance. The present paper describes the results of a prospective multicenter study aimed at comparing the clinical value of the two most widely used commercially available CgA assay kits in patients affected by neuroendocrine tumors (NETs). Two hundred sixty-one patients from 40 different centers and 99 healthy subjects were evaluated. CgA levels were measured with two different methods, a two-step immunoradiometric assay (IRMA) and an enzyme-linked immunosorbent assay (ELISA). CgA was measured centrally by two reference laboratories, one of which used IRMA and the other ELISA, and it was measured by the participating institutions with the method routinely used by each of them. The major findings of the present study were: (i) the two assays for the determination of CgA present good diagnostic performance; (ii) both assays are robust and guarantee comparable results when applied in different settings (central vs local laboratory); (iii) the negative/positive cutoff points (87 ng/mL for IRMA and 21.3 U/L for ELISA) were established according to standardized criteria; (iv) the results obtained with the two assays in basal clinical samples of patients affected by NETs show an apparently satisfactory correlation (rs = 0.843, p < 0.0001). However, a possibly clinically meaningful 36% discordance rate was found. These findings support the hypothesis that the two CgA kits might provide partially different information.
Serial monitoring of serum and urinary markers of bone regeneration may provide an indirect assessment of the activity of bone metastases. We measured serum levels of carboxyterminal propeptide of type I procollagen (PICP), a new marker of bone formation, in 236 control subjects, stratified according to age and sex, and in 122 cancer patients: 80 with breast cancer (BC) (42 with osteolytic bone metastases) and 42 with prostate cancer (PC) (31 with osteoblastic bone metastases). An inverse correlation between age and serum PICP levels was found in healthy men (r = -0.30), but not in women, PICP levels were significantly higher in patients with osteoblastic metastases compared to age-matched control subjects and patients with advanced disease not involving the skeleton. The sensitivity of PICP was 64% for detecting osteoblastic metastases, and 12% for detecting osteolytic metastases. Serum PICP determination may have a diagnostic role for osteoblastic activity.
Fourteen cancer patients with bone metastases from various primary malignancies were submitted to repeated dual X-ray absorptiometry (DEXA) scan before and after systemic antineoplastic treatments. In the nine patients with lytic lesions the Bone Mineral Density (BMD) increased after chemotherapy + pamidronate in four (by +11.2%, +7.5%, +5.0% and +6.6%, respectively), decreased in four (by -19.9%, -8.1%, -7.5%, and -7.0%, respectively) and remained unchanged in one. BMD changes paralleled variations in painful symptomatology and biochemical markers. In patients with blastic metastases the BMD on target metastatic lesions did not change after hormone therapy or chemotherapy in one case but showed a significant increase in four. BMD increase was associated to bone pain improvement and PSA decrease in two cases, and with a worsening in skeletal pain and/or serum PSA in the remaining two. Our data suggest that BMD evaluation by DEXA instrument may be a reliable tool in assessing the response of bone metastases to treatment.
BACKGROUND: Increased osteolysis usually accompanies sclerotic bone metastases from prostate cancer. This provides a rationale for the use of bisphosphonates to treat bone pain and prevent skeletal complications. METHODS: The fasting urinary levels of calcium, hydroxyproline (OHPRO), pyridinolines (PYD), deoxypyridinolines (DPYD), collagen cross-linked N-telopeptide (NTX) and the serum values of calcium, total alkaline phosphatase and relevant bone isoenzyme, bone gla protein (BGP), carboxy-telopeptide of type I collagen (ICTP) and parathyroid hormone (PTH) were determined at baseline and on the 15th, 30th, 60th and 90th days after single-dose (90 mg) pamidronate administration in 35 consecutive prostate cancer patients with bone metastases. These biochemical indices and serum interleukin 6 (IL-6) were also measured after four days in the last consecutive 17 cases. RESULTS: PYD, DPYD and NTX showed a significant decrease lasting four weeks (p<0.01, <0.01 and <0.001, respectively). OHPRO and ICTP did not change significantly. The NTX decline was greater than that of PYD and DPYD (maximum percent decrease: -71.3, -23.1 and -28.2, respectively). Bone formation markers and serum calcium did not change significantly. Serum PTH showed a rapid initial increase followed by a slow decrease (p<0.001). DPYD and NTX patterns did not correlate with changes in bone pain. As observed in the last 17 cases, the maximum osteolysis inhibition after pamidronate occurred on the fourth day after drug infusion. Serum IL-6 levels showed a short-lived decrease preceded by a transient rise on the fourth day. CONCLUSIONS: Pamidronate is able to induce a decrease in bone resorption without significantly influencing bone formation. The maximum decrease in bone resorption occurs very early. NTX is the most sensitive bone resorption marker in bisphosphonate therapy monitoring. Changes in IL-6 but not bone resorption markers may be useful in the prediction of symptomatic response.

As complete as possible a picture of the current state of cytostatic chemotherapy in the treatment of metastatic breast carcinoma is offered. Attention is therefore mainly concentrated on application modalities of this form of therapy in relation to the clinical stage of the disease and to the use of other treatment possibilities. Methods and results of cytostatic therapy are then considered. The present situation is reviewed and the pharmacological and toxic aspects of prolonged antiblastic treatment are assessed. After outlining a number of special problems relating to the treatment of CNS and pleural metastases, the personal series is presented and results, which do not differ from other reported series, reported. In conclusion, stress is laid on the importance and effectiveness of cytostatic therapy in the treatment of metastatic breast carcinoma, but extended, controlled studies are also recommended.
A panel of bone turn-over markers was assessed in 75 normocalcemic patients bearing bone metastases from breast cancer (BC), and in 25 advanced/metastatic BC patients without clinical appearance of bone involvement. 115 healthy women, stratified in three subgroups according to age served as controls. Bone formation was investigated by measuring serum carboxyterminal propeptide of type I procollagen (PICP), Bone Gla Protein (BGP, osteocalcin), bone isoenzyme of alkaline phosphatase (BALP); bone resorption by measuring serum carboxyterminal telopeptide of type I collagen (ICTP), fasting urinary hydroxyproline/creatinine (OHPro/Cr) and calcium/creatinine (Ca/Cr). In patients with bone metastases the percent of supranormal values (higher than mean plus 2 SD of the age-matched controls) ranged between 25% and 40% for indices of bone formation, about 73% for both ICTP and OHPro/Cr and about 30% for Ca/Cr. The median levels of all bone turn-over markers were higher in bone metastatic patients than in those without apparent skeletal involvement, but significance was attained only for OHPro/Cr, Ca/Cr and BALP. Supranormal levels of ICTP and OHPro/Cr were also found in about 65-70% of patients without apparent skeletal involvement. ICTP and Ca/Cr significantly correlated with bone pain score, BALP, ICTP, Ca/Cr significantly correlated with the number of tumour appearances in bone. In conclusion, the bone resorption indices, ICTP and OHPro/Cr, are much more frequently elevated than bone formation indices in BC patients with or without skeletal involvement. Their potential use in the early detection of bone metastases is hampered by the insufficient knowledge on specificity. Among the biochemical markers evaluated, Ca/Cr, ICTP and BALP, due to correlation with clinical aspects, appear the most interesting for follow-up studies.
The administration of neoadjuvant chemotherapy to breast cancer (BC) patients with operable disease allowed studies aimed of exploring the interaction between cytotoxic treatment and tumour biology in vivo. 99 patients with T2-4, NO-1, M0 primary BC received a median of 3 cycles of either CMF regimen (cyclophosphamide, methotrexate, 5-fluorouracil) or single agent epirubicin. Endocrine therapy was also concomitantly administered in the first 45 patients with estrogen receptor positive (ER+) BC. 92 ended the treatment plan. Ki67 labelling index, estrogen receptor (ER), progesterone receptor (PgR), and c-erbB-2 oncoprotein expression were evaluated immunohistochemically in tumour biopsies obtained before and after chemotherapy. At post-chemotherapy evaluation, tumour shrinkage greater than 50% was obtained in 71 patients (79.7%), 27 of them being complete responders (30.3%). The median Ki67 labelling index, which was 13% in the first biopsy, decreased to 4.5% (p < 0.001) upon mastectomy. No significant differences were observed in steroid hormone receptor and c-erbB-2 expression before and after neoadjuvant treatment. In conclusion, neoadjuvant chemotherapy, whether associated or not to endocrine therapy, leads to a significant decrease in BC proliferation without any appreciable impact on c-erbB-2 and steroid hormone receptor expression.
Randomized trials suggest that the outcome of metastatic breast cancer (BC) patients is not affected by the currently available therapies. Although response rates per se may be associated with survival prolongation, patients experiencing objective response may be those patients fated to have the longest natural disease history. The separation of responders from progressing patients after first-line chemotherapy could allow the selection of a more homogeneous subgroup in which further treatment strategies might achieve a better control of the disease. This study investigated the influence of some patient characteristics, disease characteristics, and previous treatments on the outcome of non progressing patients after first-line chemotherapy with epirubicin administration. We also evaluated the effect of the maintenance endocrine therapy in improving response rate and overall survival (OS). From May 91 to May 93, 207 patients were enrolled in a randomized trial aiming to compare the activity of epirubicin (120 mg/sqm) +/- lonidamine (600 mg/daily). Among the 169 patients attaining complete (CR), partial response (PR) or disease stabilization (SD), 65 were not randomly submitted to maintenance endocrine therapy (MET). Liver involvement, previous adjuvant chemotherapy and previous hormonal therapy (administered in adjuvant setting or for advanced disease) were found to negatively influence OS both in univariate and multivariate analysis. Differences in OS stratifying patients according to DFI, estrogen receptor status and PS did not attain statistical significance. Patients receiving MET survived significantly longer than those submitted to observation and this difference maintained the statistical significance also within patient subsets homogeneous for specific prognostic features. In conclusion, most prognostic factors for advanced BC have been confirmed in our series of patients obtaining CR, PR or SD to full dose epirubicin. The positive prognostic impact of MET is impressive and deserves confirmation in randomized studies.
A transient rise in serum alkaline phosphatase (ALP) activity (ALP flare) after androgen deprivation in prostate cancer patients with bone metastases has been previously correlated with both response to therapy and poor prognosis. In the present study we analyzed data coming from an Italian multicenter phase III, trial aimed to compare the efficacy of treatment with goserelin alone with that of goserelin plus mitomycin C. Sixty-seven bone metastatic patients were enrolled: 32 were treated with goserelin and 35 with and goserelin plus mitomycin. 58 cases had ALP measured every month; and were considered for flare assessment. Remarkably elevated ALP and PSA levels at baseline were significantly correlated with poor prognosis. The addition of mitomycin to goserelin resulted in a greater percent reduction of PSA values with respect to goserelin alone but did not augment the time to progression and overall survival. The monthly profile of ALP serum levels was superimposable in patients assigned to hormone therapy or chemotherapy plus hormone therapy. Patients showing a flare in ALP activity (transient rise > 15% in ALP values with respect to baseline at the first month) were classified as responders to therapy or as having stable disease upon PSA evaluation and/or at bone pain assessment, but had a shorter time to progression (median 12 months) in comparison to those showing a different ALP pattern (median 23 months). The measurement of flare in ALP activity during androgen suppression with or without concomitant mitomycin administration, may permit the early identification of patients who are likely to progress rapidly, and hence be candidate for more aggressive treatments.
