RESUMO

PURPOSE: The aim of the present study was to identify management strategies and outcomes of patients with stage IB1 cervical cancer with high recurrence risk. MATERIALS AND METHODS: Medical files of all consecutive patients treated between 2004 and 2017 with external beam radiotherapy and/or brachytherapy for IB1 cervical cancer, whatever the lymph node status, were retrospectively reviewed. RESULTS: Forty-two patients were included, with a median age of 49.8 years old. Median tumour size, estimated with the initial pelvic magnetic resonance imaging, was 26mm (interquartile range [IQR]=19.5-35). Histological types were mainly squamous cell carcinoma (59.5%) and adenocarcinoma (33.3%). Lymphovascular invasion was reported for 38.1% of patients. Pelvic lymph nodes were involved for eight patients (19.0%). Surgery was performed for 39 patients (92.9%). A neoadjuvant treatment was delivered for 20 patients (47.6%), an adjuvant treatment for 19 patients (45.2%) and an exclusive radiotherapy (with or without chemotherapy) followed by brachytherapy for three patients (7.1%). Pathologic complete response was achieved in 61.5% of patients. With a median follow-up of 5.8 years (IQR=2.6-9.4), five patients (11.9%) experienced a tumour relapse. The five-year disease-free survival was 79.5% (95% confident interval [CI]=66.9-94.4), the five-year overall survival was 87.8% (95% CI=77.2-99.8), and the five-year disease-specific survival was 94.2% (95% CI=86.7-100). CONCLUSION: In current clinical practice, tailored treatments are delivered, and seems to give correct therapeutic index. However, clinical trials are needed to standardise treatment according to patient characteristics and recurrence risk factors.

RESUMO

Radiation therapy plays an essential role in the treatment of invasive breast cancer. However, prophylactic treatment of supra- and infraclavicular lymph nodes is not consensual, with different treatment depending on the centres and practitioners. Clinical indications for radiotherapy of the supra- and infraclavicular lymph nodes are often the subject of a consensus. Nevertheless, radiotherapy induces some toxicity. Various techniques have been developed. To date, conformal radiotherapy allows an accurate assessment of doses to target volumes and organs at risk, but at the cost of a sometime complex delineation. This article reviews the literature on radiation of supra- and infraclavicular lymph nodes, with a special focus on technical aspects in delineation and its potential toxicity.

RESUMO

PURPOSE: To assess the benefits of magnetic resonance imaging (MRI) in the dosimetric treatment planning for prostate radiotherapy. PATIENTS AND METHODS: Ten consecutive patients have been enrolled. They were treated for a low risk prostate adenocarcinoma. A rigid superimposition was performed between MRI and scan slides obtained at time of virtual simulation, then prostate volume was delineated by four to five physicians, on TDM slides and on MRI/TDM superimposition. For each treatment plan, we assessed the impact of MRI in terms of planned treatment volume (PTV) position, individual variability of prostate delineation and doses delivered to the critical organs. The prescribed dose was 74 Gy in 37 fractions to the PTV. RESULTS: PTV delineated on TDM (V(TDM)) were 1.15 (SD 3.71) larger than volumes delineated on MRI. Prostate apex was 4.6 mm (SD 2.87) lower on TDM than on MRI. Posterior limit of the prostate was in mean 4 mm more posterior on TDM. The variability between physicians in terms of prostate delineation was lower using MRI. For apex, these variations were 6.8 mm using TDM, versus 3.3 mm using MRI. Mean rectal dose was 8 % lower with MRI, compared to delineation using TDM. CONCLUSION: Superimposition TDM/MRI improves accuracy, decreases delineation variability, and allows to spare anterior part of the rectum from irradiation. It remains unknown whether this strategy translates into clinical benefit.

RESUMO

Normofractionated radiotherapy is standard for adjuvant management of patients treated with breast conservative surgery for breast cancer. However, many elderly patients are not eligible to such strategy, either because of concurrent diseases, or because the tumor is inoperable. Several protocols of exclusive radiotherapy have been reported in the literature, frequently using hypofractionated radiotherapy and endocrine therapy. We report a case of a patient treated with exclusive endocrine and radiotherapy and address the state of the art on hypofractionated schemes for the management of elderly breast cancer patients. While hypofractionated radiotherapy does not compromise the oncologic or cosmetic outcome, there is no prospective data that assesses the place of radiotherapy for the exclusive treatment of elderly patients. This strategy should be further assessed in clinical randomized trial.

RESUMO

Radiation therapy has a major role in the management of infiltrative breast cancers. However, there is no consensus for the prophylactic treatment of the internal mammary chain (IMC), with strategies that show strong differences according to centers and physicians. Indications for internal mammary chain radiotherapy are debated, since this treatment significantly increases the dose delivered to the heart and leads to potential technical difficulties. Important prospective data recently suggested that internal mammary chain radiotherapy would not be necessary, even in cases of internal or central tumor locations, or in patients with positive axillary lymph nodes. Although these data warrant confirmation by two other prospective trials, there is evidence that the indications for internal mammary chain radiotherapy should be careful and that high quality techniques should be used for decreasing the dose delivered to the heart. This review of literature presents the state of art on the radiotherapy of internal mammary chain, with special focus on the indications, techniques, and potential toxicity.

RESUMO

BACKGROUND: This study evaluates the relation of the early oestrogen-regulated gene gabarapl1 to cellular growth and its prognostic significance in breast adenocarcinoma. METHODS: First, the relation between GABARAPL1 expression and MCF-7 growth rate was analysed. Thereafter, by performing macroarray and reverse transcriptase quantitative-polymerase chain reaction (RT-qPCR) experiments, gabarapl1 expression was quantified in several histological breast tumour types and in a retrospective cohort of 265 breast cancers. RESULTS: GABARAPL1 overexpression inhibited MCF-7 growth rate and gabarapl1 expression was downregulated in breast tumours. Gabarapl1 mRNA levels were found to be significantly lower in tumours presenting a high histological grade, with a lymph node-positive (pN+) and oestrogen and/or progesterone receptor-negative status. In univariate analysis, high gabarapl1 levels were associated with a lower risk of metastasis in all patients (hazard ratio (HR) 4.96), as well as in pN+ patients (HR 14.96). In multivariate analysis, gabarapl1 expression remained significant in all patients (HR 3.63), as well as in pN+ patients (HR 5.65). In univariate or multivariate analysis, gabarapl1 expression did not disclose any difference in metastasis risk in lymph node-negative patients. CONCLUSIONS: Our data show for the first time that the level of gabarapl1 mRNA expression in breast tumours is a good indicator of the risk of recurrence, specifically in pN+ patients.

RESUMO

A regional cancer network has been set up in the Rhône-Alpes region in France. The aim of the project is to improve the quality of care and to rationalize prescriptions in the network. In this network, we assessed the impact of the implementation of a clinical practice guidelines project by assessing the conformity of practice with the guidelines and comparing this with the conformity in an external matched control group from another French region without a regional cancer network. Four hospitals (private and public) accepted to assess the impact of the clinical practice guidelines on the management of breast and colon cancer in the experimental group and three hospitals (private and public) in the control group. In 1994 and 1996, women with non-metastatic breast cancer (282 and 346 patients in the experimental group, 194 and 172 patients in the control group, respectively) and all new patients with colon cancer (95 and 94 patients in the experimental group, and 89 and 118 patients in the control group, respectively) were selected. A controlled "before-after" study, using institutional medical records of patients with breast and colon cancer. The medical decisions concerning the patients were analyzed to assess their compliance with the clinical practice guidelines. When medical decisions were judged to be non-compliant, we verified if they were based on scientific evidence in a published article, if they were not, the medical decision was classified as having "no convincing supporting scientific evidence". The compliance rates were significantly higher in 1996 than in 1994 in the experimental group; 36% (126 out of 346) vs 12% (34 out of 282) and 46% (56 out of 123) vs 14% (14 out of 103) (P<0.001) for breast and colon cancer, respectively. Whereas, in the control group the compliance rates were the same for the two periods; 7% (12 out of 173) vs 6% (12 out of 194) (P=0.46) and 39% (49 out of 126) vs 32% (31 out of 96), P=0.19. In the experimental group, in 1994, 101 of the 282 medical decisions (36%) and 27 of the 103 (26%) for breast and colon cancer, respectively, were classified as having "no convincing supporting scientific evidence" compare with 72 out of 346 in 1996 (21%) for breast cancer, and 21 of the 123 (17%) for colon cancer P<0.05. Whereas in the control group these results were 106 out of 194 in 1994 (55%) and 90 out of 172 in 1996 (52%), P=0.65 for breast cancer and 28 out of 96 in 1994 (29%) and 30 out of 126 in 1996 (24%), P=0.36 for colon cancer. The development and implementation strategy of the clinical practice guidelines programme for cancer management results in significant changes in medical practice in our cancer network. These results would suggest that introducing guidelines with specific implementation strategy might also increase the compliance rate with the guideline and "evidence-based medicine".

RESUMO

Desmoplastic small round-cell tumors in young adults were first described in 1989. They may be revealed by an abdominal mass or a peritoneal carcinomatosis. The diagnosis and the initial treatment are based on debulking surgery. Chemotherapy using doxorubicin, ifosfamide, etoposide and cisplatin can then be proposed. Despite some initial chemosensitivity, prognosis remains poor.

RESUMO

Twenty-four patients with T1 or T2 (17 T1 N0, 7 T2 N0 not exceeding 3 cm) epidermoid carcinomas from the middle third of the mobile tongue benefit from brachytherapy with "cavaliers-legos" consisting of guide-gutters that are inserted in a rigid support (legos) and covered with a lead plate. Several advantages can be advocated with this technique: easy implantation even with local anaesthetic, no risk of bleeding, good parallelism between Iridium wires, protection of the mandible with the lead plate. Local control was achieved in 22/24 patients (92%). Four patients (16%) developed soft tissue necrosis but only one required surgical intervention and no mandibular necrosis was seen.

RESUMO

Following the experience of the German authors, the treatment of choroidal melanoma with ruthenium 106 disk was introduced in Lyon. Between 1983 and 1988, 127 patients were treated. Results are analysed on a group of 84 patients followed 18 months and more. In 72 cases a reduction of thickness was noted. It was complete in 33 cases. Enucleation was performed in 10 patients due to no response or regrowth. In 3 cases the tumor was sterilized. Five patients died of metastases, and 73 are alive, 3 of them with liver metastases. An afterloading iridium template disk was used in 8 patients. 4 of them with a tumor thickness between 6.5 and 8 mm had a good response. Edema of the fovea was observed in 21% of cases, while cataracts were very unusual with Ru 106. An enucleation was performed in 6 patients because of a complication. A useful vision may be preserved in 60% of cases. The scleral tolerance dose is close to 1,500 Gy. These results are in agreement with those of the literature and are considered to be satisfactory for tumors not exceeding 5 to 6 mm in thickness. If the tumor is located close to the fovea or the papilla, and/or if the thickness is 8 mm or more, proton beam could be a good alternative.

RESUMO

Intra operative radiation therapy is a new look at an old idea (Rich). In relation with the first experience at the Croix-Rousse Hospital with orthovoltage, a review of technical choices, surgical problems, and biological questions is presented. The analysis of literature about accumulated clinical results suggest that local control in recurrence, residual, or inoperable tumor can be obtained by combined surgery IOR, and external beam irradiation. This short experience demonstrate the feasibility of the treatment as a routine and emphasizes the need for continued study.

RESUMO

Between 1976 and 1981, 160 patients with non oat-cell carcinoma of the lung underwent a post-operative irradiation. Most of these patients presented with advanced disease, 103 of them with lymphatic involvement. Adjuvant chemotherapy was performed in 48 cases and did not improve the survival rate. Crude survival is 26% at 5 years. No severe complication was related with irradiation. The rate of local relapse was reduced by the irradiation mainly if the dose was above 45 Gy. With doses between 46 and 60 Gy the 5 year survival rate was 33% (11/34) and the rate of local failure was 18%. It is possible that such an irradiation increases the survival rate. Post-operative irradiation seemed advisable after surgery when there is a risk of local residual disease.

RESUMO

Sixty patients with infiltrating bladder cancer were treated by partial cystectomy and iridium radiotherapy between 1977 and 1982. Actuarial 5-year survival was 90% for pT1, 51% for pT2 and 34% for pT3, bladder treatment being unsuccessful in 6 cases (11%). Long-term functional results were satisfactory. Iridium provides better radioprotection than radium and stricter dosage can be established. This conservative treatment for infiltrating bladder cancer is particularly indicated for pT1 and pT2 tumors, as single lesions and with a largest diameter not exceeding 4 cm. Results are better in cases with tumors of the mobile portion of bladder, the 5-year survival in these selected cases being 85% with a minimum of sequelae. This treatment may be used, generally combined with external radiotherapy, for tumors infiltrating deeply into muscle and more distant tissues.

RESUMO

Since 1975, 36 patients with squamous cell carcinoma of the penis have been treated with 192 Iridium at the Centre Léon Bérard: 17 T1 lesions, 18 T2 lesions and one T3 lesion. The tumor was less than 4 cm in diameter in 31 cases. Two patients presented with local recurrences after local excision and/or external beam irradiation with 60 Cobalt. In 32 patients followed for more than one year, the rate of local control was 84% (27/32). Five local failures were controlled by subsequent salvage surgery. The rate of severe complications is 25% (8/32): 2 urethral stenoses, 4 necroses, and 2 severe fibrosis. Conservation of a functional organ was possible in 72% of cases (23/32). Amputation was necessary in the 5 patients with lesions of more than 4 cm, because of local failure or painful complications. Ten patients had palpable inguinal lymph nodes, which were found to be involved in 4 cases. Three were controlled by combined radiotherapy and surgery. Among patients off any lymphadenopathy at the time of diagnosis, only one subsequently developed an inguinal metastasis which was controlled by radiotherapy and surgery. The disease-free survival rate was 81% at 3 years (22/27) and 75% at 5 years (12/16). Only one patient died of carcinoma. Curietherapy with 192 Iridium is very suitable treatment for cancers of the penis less than 4 cm in diameter. In most patients, the quality of life will be better than with primary surgical amputation, because sexual function is preserved.
