A phase II trial with cisplatin-paclitaxel cytotoxic treatment and concurrent external and endocavitary radiation therapy in locally advanced or recurrent cervical cancer.

BACKGROUND: Five randomized studies have demonstrated a beneficial effect of adding cisplatin-based chemotherapy to radiation therapy in the treatment of cervical carcinoma. In the present phase II study, we evaluated the response and toxicity of cisplatin-Taxol chemotherapy combined with concomitant radiotherapy in patients with locally advanced cervical carcinoma (LACC) and locally recurrent cervical carcinoma (LRCC). PATIENTS AND METHODS: In 2000, this phase II study was initiated with a chemotherapy regimen of cisplatin (75 mg/m(2)) and Taxol (175 mg/m(2)) every 21 days, for four cycles, concomitant with external radiotherapy and high-dose-rate brachytherapy. Pelvic radiotherapy was started 2 weeks after the first chemotherapy cycle, while the first brachytherapy insertion was carried out during the fourth chemotherapy cycle. SCC marker was determined before treatment and after every chemotherapy cycle. RESULTS: All of the 27 patients treated achieved a complete clinical response. Two patients with LACC experienced distant recurrence 22 and 24 months after complete response, respectively, and 1 patient with LRCC had local progression 6 months after the end of radiotherapy. Although generally tolerable, neutropenia grade 3-4 in 4 patients and anemia grade 3 in 2 patients were observed, and 1 patient experienced grade 2 neurotoxicity; toxicity due to radiotherapy was moderate. CONCLUSIONS: Concomitant cisplatin-Taxol chemoradiotherapy seems to be well tolerated, and results, even in this small series, are encouraging.

Lymphatic microsurgery for the treatment of lymphedema.

One of the main problems of microsurgery for lymphedema consists of the discrepancy between the excellent technical possibilities and the subsequently insufficient reduction of the lymphoedematous tissue fibrosis and sclerosis. Appropriate treatment based on pathologic study and surgical outcome have not been adequately documented. Over the past 25 years, more than 1000 patients with peripheral lymphedema have been treated with microsurgical techniques. Derivative lymphatic micro-vascular procedures has today its most exemplary application in multiple lymphatic-venous anastomoses (LVA). For those cases where a venous disease is associated to more or less latent or manifest lymphostatic pathology of such severity to contraindicate a lymphatic-venous shunt, reconstructive lymphatic microsurgery techniques have been developed (autologous venous grafts or lymphatic-venous-Iymphatic-plasty - LVLA). Objective assessment was undertaken by water volumetry and lymphoscintigraphy. Subjective improvement was noted in 87% of patients. Objectively, volume changes showed a significant improvement in 83%, with an average reduction of 67% of the excess volume. Of those patients followed-up, 85% have been able to discontinue the use of conservative measures, with an average follow-up of more than 7 years and average reduction in excess volume of 69%. There was a 87% reduction in the incidence of cellulitis after microsurgery. Microsurgical lymphatic-venous anastomoses have a place in the treatment of peripheral lymphedema and should be the therapy of choice in patients who are not sufficiently responsive to nonsurgical treatment. Improved results can be expected with operations performed earlier at the very first stages of lymphedema.

Is there a role for microsurgery in the prevention of arm lymphedema secondary to breast cancer treatment?

The secondary lymphedema of the upper limb (post-mastectomy lymphedema) has an incidence, in patients who underwent axillary lymphadenectomy for breast cancer, between 5 to 25%, up to 40% after radiotherapic treatment. We studied 50 patients treated for breast cancer. The patients were divided in two groups of 25 each, comparable for age, sex, pathology and treatment and followed up to 5 years after operation for breast. One group of 25 patients was controlled only clinically (physical examination, water volumetry) at 1-3-6 months and 1-3-5 years from breast cancer treatment. The other group of 25 patients was followed also by lymphatic scintigraphy performed pre-operatively and after 1-3-6 months and 1-3-5 years from operation. In the first group, followed only clinically, lymphedema appeared in 9 patients after a period variable from 1 week to 2 years, with highest incidence between 3 and 6 months. In the second group of 25 patients, the preventive therapeutic protocol allowed to have a clinically evident arm lymphedema only in 2 patients. The comparison of the two groups of 25 patients proved a statistically significant difference in the appearance of arm secondary lymphedema (p = 0.01, using Fisher's exact test). The diagnostic and therapeutic preventive procedures allow to reduce the incidence rate of lymphedema significantly, in comparison with patients who did not undergo this protocol of prevention.

Adjuvant chemotherapy of bladder cancer.

BACKGROUND: Bladder cancer is one of the most common genitourinary cancer. 1/3 of patients presents with invasive disease. Radical cystectomy is the standard treatment for patients with muscle invasive disease: although local treatment can be curative, about 50% of patients will develop distant metastases. Optimal treatment for high risk patients includes local and perioperative systemic therapy (adjuvant or neoadjuvant chemotherapy). PATIENTS AND METHODS: We performed a review of clinical trials and metanalysis of adjuvant treatment for muscle-invasive bladder cancer. RESULTS: Data from single published trials of adjuvant chemotherapy (CT) are not univocal, and several methodological problems were found. A recent meta-analysis of individual patient data (IPD) from all eligible published and unpublished trials, found that adjuvant chemotherapy administration provides a significant survival and disease free survival advantage. Two large, multi-center, randomized trials are on-going to clarify the role of post-operative CT. CONCLUSIONS: A trend in favour of adjuvant chemotherapy comes out from some of the trials reviewed by us and by the metanalysis performed by the ABC collaborative group. However it is not clear yet which patients might derive the maximum benefit from such an approach and which ones might be safety candidate to deferred treatment, on relapse. The incoming results of the EORTC trial and of the Italian trial which are currently comparing the value of early vs. deferred treatment of patients at higher risk of relapse will probably provide an adequate answer to this question. Outside clinical trials, the potential benefit of adjuvant chemotherapy should be appropriately weighted versus the putative hazards and decision making appropriately tailored in the individual patients according to the aggressiveness of his/her disease and the presence of comorbidities.

Switching to anastrozole versus continued tamoxifen treatment of early breast cancer. Updated results of the Italian tamoxifen anastrozole (ITA) trial.

BACKGROUND: Tamoxifen, for many years the 'gold standard' in the adjuvant setting for the management of endocrine sensitive early breast cancer, is associated with an increased risk of endometrial cancer and other life-threatening events. Moreover, many women relapse during or after tamoxifen therapy due to the development of resistance. This provided the rationale for a switching trial with anastrozole, the updated results of which are reported here. PATIENTS AND METHODS: This trial investigated the efficacy of switching to anastrozole for women already receiving tamoxifen. After 2-3 years of tamoxifen treatment, postmenopausal, node-positive, ER-positive patients were randomized to receive either anastrozole 1 mg/day or to continue tamoxifen, 20 mg/day, giving a total duration of 5-years treatment. The primary end point was disease-free survival and secondary endpoints were event-free survival, overall survival and safety. RESULTS: A total of 448 patients were enrolled. At a median follow-up time of 64 months (range 12-93), 63 events had been reported in the tamoxifen group compared with 39 in the anastrozole group [HR 0.57 (95% CI 0.38-0.85) P = 0.005]. Relapse-free and overall survival were also longer in the anastrozole group [HR 0.56 (95% CI 0.35-0.89) P = 0.01 and 0.56 (95% CI 0.28-1.15) P = 0.1]. However, the latter difference was not statistically significant. Overall more patients in the anastrozole group experienced at least one adverse event (209 versus 151: P = 0.000). However, numbers of patients experiencing serious adverse events were comparable (37 versus 40, respectively: P = 0.7). CONCLUSIONS: Switching to anastrozole after the first 2-3 years of treatment was confirmed to improve event-free and relapse-free survival of postmenopausal, node-positive, ER-positive early breast cancer patients already receiving adjuvant tamoxifen.

Prevalence of oedema of the lower limbs in multiple sclerosis patients: a vascular and lymphoscintigraphic study.

The aim of the study was to evaluate the frequency of oedema of the lower limbs in multiple sclerosis (MS) patients utilizing a multidisciplinary approach. A total of 205 patients with definite MS were included in the study. Seventy-five were male and 130 female, with a mean age of 50.53, mean Expanded Disability Status Scale (EDSS) score of 5.27 and mean disease duration of 16.6 years. Seventy-one patients had a relapsing-remitting (RR) disease course, 85 were secondary progressive (SP) and 49 were primary progressive (PP). Ninety-three patients (45%) showed oedema at the examination. EDSS, disease duration and disease course, but not gender, were statistically different between oedema and non-oedema patients. Out of 93 patients with oedema, 69 agreed to undergo a vascular examination. Of 69 patients, 45 (65.2%) had a CEAP score (specific rating scale for oedema) of 3 (presence of oedema) and 24 (34.8%) had a score of 4 (presence of a trophic disorder). Out of 69 subjects, 33 agreed to undergo a lymphoscintigraphy, which was normal in only 29 extremities out of 66. Lower limb oedema is common in MS patients, especially in those with reduced mobility. Early screening is advised in patients with an elevated EDSS.

Lymphodynamics in the fetus and newborn.

Body fluid is distributed among three major fluid spaces: plasma, interstitial fluid, and intracellular fluid. The distribution of fluid in each of these compartments is dramatically different in the fetus and newborn compared to the adult. In addition, the amniotic fluid that surrounds the fetus may also be considered an extension of the extracellular space of the fetus. The purpose of this review is to discuss the complex mechanism that regulates volume in the fetus and newborn as well as the regulation of fluid distribution between the plasma and interstitial fluid, while placing special emphasis on the role the lymphatic system plays in mediating and maintaining this distribution.

Evaluation of tamoxifen and anastrozole in the prevention of gynecomastia and breast pain induced by bicalutamide monotherapy of prostate cancer.

PURPOSE: To determine whether tamoxifen or anastrozole prevents gynecomastia and breast pain caused by bicalutamide (150 mg) without compromising efficacy, safety, or sexual functioning. PATIENTS AND METHODS: A double-blind, placebo-controlled trial was performed in patients with localized, locally advanced, or biochemically recurrent prostate cancer. Patients (N = 114) were randomly assigned to either bicalutamide (150 mg/d) plus placebo or in combination with tamoxifen (20 mg/d) or anastrozole (1 mg/d) for 48 weeks. Gynecomastia, breast pain, prostate-specific antigen (PSA), sexual functioning, and serum levels of hormones were assessed. RESULTS: Gynecomastia developed in 73% of patients in the bicalutamide group, 10% of patients in the bicalutamide-tamoxifen group, and 51% of patients in the bicalutamide-anastrozole group (P < .001); breast pain developed in 39%, 6%, and 27% of patients, respectively (P = .006). Baseline PSA level decreased by > or = 50% in 97%, 97%, and 83% of patients in the bicalutamide, bicalutamide-tamoxifen, and bicalutamide-anastrozole groups, respectively (P = .07); and adverse events were reported in 37%, 35%, and 69% of patients, respectively (P = .004). There were no major differences among treatments in sexual functioning parameters from baseline to month 6. Elevated testosterone levels occurred in each group; however, free testosterone levels remained unchanged in the bicalutamide-tamoxifen group because of increased sex hormone-binding globulin levels. CONCLUSION: Anastrozole did not significantly reduce the incidence of bicalutamide-induced gynecomastia and breast pain. In contrast, tamoxifen was effective, without increasing adverse events, at least in the short-term follow-up. These data support the need for a larger study to determine any effect on mortality.

Pulmonary lymphangiectasia.

Congenital pulmonary lymphangiectasia (PL) is a rare developmental disorder involving the lung and is characterized by pulmonary subpleural, interlobar, perivascular, and peribronchial lymphatic dilatation. Both frequency and etiology are unknown. PL presents at birth with severe respiratory distress, tachypnea, and cyanosis, with a very high mortality rate at or within a few hours of birth. At birth, mechanical ventilation and pleural drainage are nearly always necessary to obtain a favorable outcome of respiratory distress. Home supplemental oxygen therapy and symptomatic treatment of recurrent cough and wheeze are often necessary during childhood, sometimes associated to prolonged pleural drainage. Recent advances in intensive neonatal care have changed the previously nearly fatal outcome of PL at birth. Patients affected by PL who survive infancy present medical problems which are characteristic of chronic lung disease.

Combined treatment with chemotherapy and radiotherapy in high-risk FIGO stage III-IV endometrial cancer patients.

OBJECTIVES: We reviewed our series of very advanced FIGO stage III-IV endometrial cancer patients to assess the efficacy and toxicity of a platinum- and doxorubicin-containing chemotherapy followed by conventional radiotherapy. METHODS: Forty-five patients with advanced FIGO stage III and IV endometrial cancer have been treated, after surgery, with four courses of chemotherapy containing cisplatin 50 mg/m(2), epidoxorubicin 60 mg/m(2) and cytoxan 600 mg/m(2) (day 1 every 21 days) in association with conventional external pelvic radiotherapy (50 Gy, with a 2 Gy daily dose administered with "box technique"). RESULTS: Chemotherapy was well tolerated: WHO grade 4 neutropenia, without fever or other symptoms, has been recorded in six patients (8.8%) at nadir, but no patient required hospitalization or colony-stimulating factors support during chemotherapy. Radiotherapy timing was not delayed by systemic treatment. Toxicities observed during radiation treatment are superimposable to those referred for not pretreated patients. At a median follow-up time of 63 months (range 4-112), 18 patients progressed and 16 patients have died: actuarial 9 years progression-free survival and survival are 30% and 53%, respectively. CONCLUSIONS: The addition of chemotherapy to radiotherapy seems to be an effective and safe way to treat this subset of endometrial cancer patients.

Serum enterolactone levels and the risk of breast cancer in women with palpable cysts.

Low levels of lignans, namely enterolactone, have been reported to be associated with an increased risk of breast cancer in the general female population. We assessed, retrospectively, the relationship between serum enterolactone concentrations and the occurrence of breast cancer in women with palpable cysts. The levels of enterolactone in cryopreserved serum aliquots, obtained from 383 women with palpable cysts at the time of their first cyst aspiration, were measured using a time-resolved fluoroimmunoassay (TR-FIA). After a median follow-up time of 6.5 years (range 0.5-12.75 years), 18 women were found to have developed an invasive breast cancer. Median values of serum enterolactone were significantly lower in women who subsequently developed breast cancer: 8.5 nM/l versus 16.0 nM/l: P=0.04. Odd Ratios (OR) for breast cancer were: 0.36 (P=0.03), 0.57 (P=0.3) and 0.38 (P=0.25) for 25th (8 nM/l), 50th (16 nM/l) and 75th (24 nM/l) percentile values, respectively. The receiver operating characteristic (ROC) analysis showed a satisfactory accuracy for enterolactone as a breast cancer risk indicator (area under the curve (AUC)=0.64: P=0.04). Logistic regression analysis confirmed that the enterolactone concentration had a strong protective effect on the breast cancer risk. These findings may have important clinical implications with regard to interventional diet-focused chemo-preventive trials.

Multimodal imaging in the congenital pulmonary lymphangiectasia-congenital chylothorax-hydrops fetalis continuum.

We report on three infants with congenital chylothorax (CC) and congenital pulmonary lymphangiectasia (CPL). CPL appears to be a characteristic pathological finding in CC. Through the use of lymphoscintigraphy and computed tomography, this study suggests that CC and CPL are strongly correlated entities and that the dysplasia of the lymphatic system results in a pulmonary lymphatic obstruction sequence. The initial microscopic dilatation of the lymph channels may lead to progressive weeping of lymphatics and, consequently, to pleural effusion. Non-Immune Hydrops Fetalis (NIHF) may be the final consequence of impaired systemic venous return and may help to explain pleural-pulmonary involvement in this generalized lymph-vessel malformation syndrome.

Vein graft interposition in treating peripheral lymphoedemas.

The technique of interposed vein grafts (Lymphatic-Venous-Lymphatic Plasty: LVLA) consists in using autologous vein grafts to reconstruct lymphatic pathways where there is a block to the lymphatic circulation of the limb due to a congenital or acquired reason. The venous segment represents a sort of "bridge" between afferent and efferent lymphatic collectors. The study aims at evaluating long-term results of the treatment of peripheral lymphoedemas by the microsurgical reconstructive technique of LVLA. The results proved to be positive also in the long term after microsurgical operation. The follow-up was performed by water volumetry and isotopic lymphography. This technique of interposed vein grafts allows peripheral lymphoedemas to be treated when derivative lympho-venous shunts can not be used due to an impaired venous circulation in the same lymphoedematous limb.

Ifosfamide in urologic cancer.

The therapeutic activity of ifosfamide in urologic tumors has been reviewed. Ifosfamide has definite activity in nephroblastoma, where it represents the treatment of choice for children who are not cured by front-line chemotherapy, and for the adults who are diagnosed with this uncommon disease. Definite therapeutic activity has also been shown in patients with urothelial tract malignancies and it represents a major option for patients failing first-line cisplatin-based chemotherapy. However, promising results have been achieved in chemo-naïve patients in combination with taxanes or gemcitabine, though at the price of relevant toxicity. A modest activity has been shown by ifosfamide in renal cancer (including the sarcomatoid variant) and in hormone-refractory prostate cancer, which unfortunately respond poorly to cytotoxic chemotherapy. No results of ifosfamide in penile carcinoma are available so far.

Lymphedema and microsurgery.

Lymphedema is often diagnosed by its characteristic clinical presentation. In some cases, however, instrumental investigations are necessary to establish the diagnosis, particularly in early stages of the disease. One of the primary problems for microsurgery in treating lymphedema consists of the discrepancy between the excellent technical possibilities and the insufficient results in reduction of lymphedematous tissue fibrosis and sclerosis. Long-term results indicate that microsurgical operations have a valuable place in the treatment of obstructive lymphedema (primary or secondary) and should be the treatment of choice in these patients. Improved results can be expected with earlier microsurgical operations because patients referred earlier usually have less lymphatic disruption and fibrotic tissue. Advanced diagnostic methods and improvements in operation techniques have modified indications for surgical therapy of lymphedema. This article systematically reviews the published literature on the microsurgical treatment of lymphedema to the present.
