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.

Carrier-mediated uptake and phloem systemy of a 350-Dalton chlorinated xenobiotic with an alpha-amino acid function.

In a previous paper we have shown that epsilon-(phenoxyalkanecarboxylyl)-L-Lys conjugates are potent inhibitors of amino acid transport systems and that it is possible to modulate the uptake inhibition by hydrophobic or hydrophilic additions in the 4-position of the aromatic ring (J.F. Chollet, C. Delétage, M. Faucher, L. Miginiac, J.L. Bonnemain [1997] Biochem Biophys Acta 1336: 331-341). In this report we demonstrate that epsilon-(2,4-dichlorophenoxyacetyl)-L-Lys (2,4D-Lys), one of the largest molecules of the series and one of the most potent inhibitors, is a highly permeant conjugate. Uptake of 2,4D-Lys by broad bean (Vicia faba) leaf discs is mediated by an active carrier system (Km1 = 0.2 mM; Vmax1 = 2.4 nmol x cm(-2) x h(-1) at pH 5.0) complemented by an important diffusive component. Among the compounds tested (neutral, basic, and acidic amino acids, auxin, glutathione, and sugars), only the aromatic amino acids clearly compete with 2,4D-Lys. The conjugate accumulates in the vein network, is exported toward the growing organs, and exhibits a distribution pattern different from that of the herbicide moiety. However, over time 2,4D-Lys progressively splits into 2,4D and lysine. Analyses by high-performance liquid chromatography and liquid scintillation spectrometry of the phloem sap collected from the castor bean system, used as a systemy test, indicate decreasing capacities of 2,4D, 2,4D-Lys, and glyphosate, respectively, to move from the epidermis cell wall to the sieve element. Our results show that it is possible to design synthesis of large-size xenobiotics (approximately 350 D) with a lipophilic pole, exhibiting high mobility within the vascular system.

Intraoperative radiation therapy combined with limited lymph node resection in gastric cancer: an alternative to extended dissection?

PURPOSE: To describe the results of a series of 63 Western patients presenting with gastric adenocarcinoma and treated with surgery and intraoperative radiation therapy (IORT) over a 8-year period and to discuss the role of IORT when combined with limited lymph node dissection. METHODS AND MATERIALS: From 1986 to 1993, 63 patients with gastric adenocarcinoma have been operated in the department of radiation oncology of the Hospices Civils de Lyon. The stage was: I in 17, II in 11, IIIA in 9, IIIB in 20, and IV in 6. The lymph node dissection was considered to be limited in 56 patients and extended in 7. The IORT dose ranged from 12 to 23 Gy (median: 15). Thirty patients also underwent a postoperative external beam irradiation with a standard dose of 44-46 Gy. RESULTS: The postoperative mortality rate was 4.8%. The 5-year overall survival in the entire series was 47% and was 82, 55, 78, 20, and 0% in Stages I, II, IIIA, IIIB, and IV, respectively. Loco-regional relapse occurred in 15 of 63 patients and metastases in 15 of 63. CONCLUSION: In Western patients treated by gastrectomy for adenocarcinoma of the stomach, IORT combined with limited lymph node dissection may provide overall survival similar to that observed after gastrectomy with extended lymph node dissection but with less postoperative mortality.
