Efficiency of auricular acupuncture in climacteric symptoms after cancer treatments.

OBJECTIVES: This paper aims to highlight the efficiency of auriculotherapy in the treatment of hot flushes, especially in cancer-related menopausal transition. METHODS: We used systematically collected data from patients in 2014 in a medical oncology practice. The treatment was made according to the guidelines of The Inter-University Diploma and the cartography of the World Health Organization; data on satisfaction were collected orally. RESULTS: In 2014, 49 patients, among whom 41 had cancer, were treated for hot flushes. Although it is not recommended to treat several symptoms during the same session, we dealt with 1.7 symptoms per session on average. Sixty-nine percent of the patients were satisfied. We lacked data for nine patients, who did not come to the minimal recommended number of treatments (three). Only one patient among those who did not observe any improvement received three treatments. CONCLUSIONS: Auricular acupuncture is a safe and cheap method to treat hot flushes. It has been effective in numerous and various cases, among which were patients who presented cancer-related menopausal symptoms. It may be applied for a large variety of other symptoms.

Radiation therapy of the primary tumour and/or metastases of digestive metastatic cancers.

Metastatic gastrointestinal cancer is not an uncommon situation, especially for pancreatic, gastric, and colorectal cancers. In this setting, few data are available on the impact of the treatment of the primary tumour. Oligometastatic disease is associated with longer survival in comparison with more advanced disease. Metastasis-directed therapy, such as stereotactic body radiotherapy, seems related to better outcomes, but the level of evidence is low. In most tumour locations, prospective data are very scarce and inclusion in ongoing trials is strongly recommended.

Metastases-directed radiotherapy in castration resistant oligo metastatic prostate cancer: A multicentric retrospective study from the French group COLib.

Oligometastases are defined as a number of detectable metastases less or equal to 5. In castrate-resistant oligo metastatic prostate Cancer (CR oligoM PC), Metastases-Directed Ablative radiotherapy (MDRT) is poorly investigated. Our study retrospectively reviewed the cases of CR oligoM PC treated with MDRT in 8 French high-volume radiotherapy centers. OS and PFS are defined as the delay between the first day of MDRT and death (OS) or progression according to PCWG criteria (PFS). OS and PFS are evaluated according to Kaplan Meyer, curves are compared with log rank test. Logistic regression was used to identify predictive factors for outcome: bone versus node metastasis, ISUP grade, PSA doubling Time (PSADT) at the time of MDRT, time to castration resistance. 107 patients were included in the study, among those 197 metastases received MDRT. For the overall population, the median follow-up was 25.2 months (1,4-145). OS was 93 % at 2 years and 81,4% at 3 years. At 2 years, 100 % of patients with node-only metastasis were alive versus 88,7% among those who have bone metastases (p = 0,72). The median PFS was 12,6 months (IC 95 % [9,6; 17]), with no difference among patients with node only disease versus the rest of the cohort. The PFS was 18,2 months (10,0; 32,4) in patients with PSADT >6 months versus 10,7 months (8,9; 14,3) when PSADT was inferior to 6 months. However, this difference did not reach significant. We did not find a correlation neither between ISUP grade (1-2 versus 3-4-5) and PFS, nor between hormone-sensitivity duration and PFS. Patients receiving MDRT for CR oligoM PC have a good prognosis with 81,6% OS at 3 years. PSA DT longer than 6 months could be related to better PFS. MDRT strategy could postpone the onset of new systemic treatment with median PFS >1 year.

Stereotactic body radiation therapy for adrenal gland metastases: A multi-institutional outcome analysis.

Aim: The adrenal gland is a common site of metastasis with a rate of up to 27% in autopsy series. The incidence of these metastases is increasing due to greater use of Positron Emission Tomography scans and improved overall survival of patients with metastatic cancers. Stereotactic body radiation therapy (SBRT) is a non-invasive treatment option for metastasis. The aim of this study is to assess prognostic factors influencing local control, progression-free and overall survival in oligometastatic patients treated with SBRT for an adrenal metastasis. Methods: In this multicentric retrospective study, we included patients with adrenal metastases treated with SBRT between 2010 and 2021 in eleven french centers. All primary tumors were included. Results: A total of 110 patients treated for 121 adrenal lesions were included. Non-small-cell lung cancer was the predominant histologic type (55.4 %). Eighty-two percent of patients had at least 2 metastatic sites. The median Planning Target Volume was 70 cm3 with a median prescription dose of 40 Gray (Gy). The mean Biologically Effective Dose (BED) 10 dose was 74.2 Gy. Local control at 1 and 2 years was 85.9 % and 72.5 % respectively. The median overall survival and progression-free survival were 31.6 and 8.5 months respectively. Local control was significantly improved by systemic treatment one month before or after SBRT (p = 0.009) and by a BED10 greater than or equal to 50 Gy (p = 0.003).In multivariate analysis, oligometastatic presentation (p = 0.009) and a metachronous metastatic presentation (p = 0.008) were independent factors for progression-free survival.Tolerance was excellent, no grade 3 and 4 toxicities were described due to SBRT. Conclusion: Stereotactic radiotherapy of adrenal metastases makes possible a local control of more than 85% at one year and was well tolerated. The factors influencing survival in oligometastatic patients still need to be found in order to better select those who benefit the most from this type of treatment.

[Impact of IMRT for neoadjuvant rectal cancer?] / Quel apport de la modulation d'intensité pour la radiothérapie des cancers du rectum ?

The standard management of locally advanced rectal tumors as cT3-T4 and/or N0/N1 is based on preoperative treatment combining radiotherapy of 45 to 50Gy and chemotherapy based on 5-fluorouracil. Intensity-modulated radiotherapy has already shown its interest compared to conformal radiotherapy in other locations, like in pelvic cancer. The role of intensity-modulated radiotherapy in the pre/postoperative treatment of rectal cancers is not a standard of care. Published studies showed its feasibility with the objective of less toxicity with equivalent efficacy.

[Preoperative chemoradiotherapy for rectal cancer: experience from one centre]. / Chimioradiothérapie préopératoire du cancer du rectum : expérience d'un centre.

PURPOSE: In recent decades, the management of rectal cancer has been significantly improved by optimizing the surgical treatment with the total mesorectal excision and the development of neoadjuvant radiotherapy with or without chemotherapy. In this study, we investigated the impact of changes in practice over a period of 15 years in an expert centre. PATIENTS AND METHODS: A monocentric study was conducted retrospectively on cT3-resectable T4 patients who received chemoradiotherapy for a locally advanced rectal adenocarcinoma between 1993 and 2008. We studied sphincter preservation, pathological complete response (ypT0), survival, and toxicities by different concomitant chemotherapy and treatment period. RESULTS: Among the 179 patients who had a chemoradiotherapy, 56.4% were received concomitant 5-fluoro-uracil-leucovorin, 28.5% with concomitant capecitabine, and 15.1% with concomitant oxaliplatin and capecitabine. The average dose of radiotherapy was 45 Gy (25×1.8 Gy). Five-year disease-free survival was 74.3% and overall survival 68.8%. The rate of local recurrence and distant metastases were 6.1 and 23.6%. In multivariate analysis, concomitant chemotherapy oxaliplatin and capecitabine improved the pathological complete response rate (ypT0; capecitabine: 6%, 5-fluoro-uracil-leucovorin: 10.3%, capecitabine-oxaliplatin: 22.2%), but not significantly (P=0.12) and with more toxicities, and treatment interruptions. Sphincter preservation rate was not improved significantly during the study period (1993-2004 vs. 2005-2008), but disease-free survival improved from 72.2% up to 87.5% (P=0.03). CONCLUSION: Our results are consistent with those published in the literature. Concomitant chemotherapy with 5-fluoro-uracil or capecitabine remains the standard scheme. Upfront chemotherapy, before chemoradiotherapy, should be investigated with regard to the predominance of metastasis.

Management of patients with head and neck tumours presenting at diagnosis with a synchronous second cancer at another anatomic site.

AIMS: To understand management strategies and outcomes of patients diagnosed with a head and neck tumour and a synchronous second cancer developed at another anatomic site. MATERIALS AND METHODS: Retrospective analysis of all patients diagnosed with a head and neck carcinoma and a synchronous cancer and engaged in curative-intent treatments. To evaluate therapeutic strategies, each patient's treatment process was divided into sequential therapeutic modalities and corresponding targets (head and neck and/or synchronous tumour) were identified. Patient outcome was analysed with an intent-to-treat approach. RESULTS: Forty-three patients were entered into the study (mean age=57.4 years). Synchronous tumours concerned the lung (57.8%), oesophagus (31.1%) or other sites (11.1%). Treatments were complex, including one to four consecutive modalities, with a mean duration of 4.6 months. When both tumours were advanced, treatments were frequently initiated with dual-spectrum chemotherapy (66.7%). In other situations, a locoregional treatment was often (81.1%) proposed immediately. When both tumours were in early stages, this initial locoregional treatment could be extended to target both tumours together (30.0%). For patients whose tumours differed in severity, this locoregional treatment targeted only one tumour (85%); priority was given to the most advanced one (76.5%). Nine patients had definitive treatment interruption. Associated risk factors were a low body mass index (P=0.03) and advanced-stage tumours (P=0.01). Thirty-one patients died (72.1%) with a median time to death of 7.7 months. The median follow-up for survivors was 46.2 months. Three-year overall survival was 33.9%. Low body mass index (P=0.001), advanced-stage synchronous tumours (P=0.03) and oesophageal primaries (P=0.03) altered the overall survival. Three-year locoregional and metastatic progression-free survival was 40.8 and 62.5%, respectively. Low body mass index (P=0.01) and advanced-stage synchronous tumours (P=0.01) increased the risk of disease failure. CONCLUSIONS: Head and neck tumours diagnosed with a synchronous cancer are a complex challenge. Despite a severe prognosis, patients who are not underweight, presenting with lower-stage tumours (especially the synchronous tumour) and without oesophageal involvement could most benefit from aggressive treatments.
