The "reversed" treatment approach for synchronous liver metastases and colorectal cancer. Feasability and first results

Background: The « reversed treatment» approach inverts the treatment sequence of¦advanced synchronous colorectal liver metastases - i.e. the liver metastasis is¦treated first, followed by resection of the primary tumor. Chemotherapy is performed¦before and after liver surgery. We recently started to use a reversed treatment¦approach in selected patients. The aim of this study is to critically assess this new¦treatment modality.¦Methods: Nine patients (7 male, 2 female, mean age 62 years) benefited from this¦new treatment between November 2008 and May 2010. The data were collected¦retrospectively.¦Results: All patients responded to the neoadjuvant chemotherapy. The median¦number of liver metastases was 6 (range 1 - 22). The median size of the largest liver¦metastases was 4.3 cm (range 2.6 - 13 cm). Three patients had portal vein¦embolization prior to liver surgery. Two patients could not complete the treatment.¦One had to undergo emergency surgery for occluding colonic tumor. The second one¦showed liver recurrence before starting the adjuvant chemotherapy. The seven¦patients who completed the treatment are still alive after a median time of 27 months¦(range 17 - 37 months). Seven of them had recurrence (1 rectal, 6 liver). The median¦disease-free survival was 9 months (range 0 - 17 months).¦Conclusion: Based on our preliminary experiences, the reversed strategy shows¦encouraging results for the treatment of advanced synchronous colorectal liver¦metastases in well selected patients. The treatment was generally well tolerated and¦long term survival seems to be prolonged.

The young infant's triangular communication in the family : access to threesome intersubjectivity ? Conceptual considerations and case illustrations

During these last decades, the notion of primary intersubjectivity has gained acceptance among developmentalists and clinicians. But a new challenge is put out to our models by recent findings on the triangular competence of the very young infant, or her capacity to simultaneously communicate with two partners at a time. This discovery raises the question of a collective form of intersubjectivity. Findings on the triangular competence of the 3- to 4-month-old interactions with father and mother in different contexts of the Lausanne trilogue play situation are reviewed and illustrated, with a view to examine whether it is based on a dyadic or triangular program and whether conditions for a threesome form of primary intersubjectivity are fulfilled. The discussion focuses on the revisions of the theory of intersubjectivity, of developmental theory, and of clinical practice these findings call for, pointing toward a three -person psychology too.

Variations in fathers' discourse on fatherhood and in family alliances during infancy

The aim of this pilot study is to analyse the discourse of fathers of toddlers concerning fatherhood and the link between some particularities in the discourse and family alliance. The sample consists of 13 Swiss first time fathers (5 fathers of girls and 8 of boys). In order to evaluate the paternal discourse, the fathers were given a semi-structured interview, which was later analysed using the research package Alceste. The family alliance, i.e., the degree of coordination among the partners when executing a task together, was assessed through the Lausanne Trilogue Play (Fivaz-Depeursinge & Corboz-Warnery, 1999). The main results indicated an interesting link between classes of paternal discourse grouped around the following themes "affective relationship", "daily routine" and "educational goals", and the family alliance (defined in two major categories; functional and problematic alliances). Finally, clinical perspectives on links between paternal representations and family functioning at an interactive level are discussed

Mir211 Is Dysregulated In Conjunctival Melanocytic proliferations

Purpose Downregulation of TRPM1 mRNA, a transient receptor potential cation channel, has been identified in highly metastatic cutaneous melanoma cell lines. TRPM1 mRNA expression is inversely correlated with skin melanoma metastases. Recent evidence has demonstrated that the tumor suppressive activity of TRPM1 is due to miR211 situated in intron 6 of TRPM1. As we have previously identified a downregulation of TRPM1 mRNA expression in conjunctival melanoma, we decided to assess miR211 expression and its potential target gene IGF2R and KCNMA1 in conjunctival melanocytic proliferations. As MITF has been shown to regulate both TRPM1 and mir211 expression, we also assessed MITF expression in our series. Methods Expression of miR211 was assessed by in situ hybridization in 14 conjunctival naevi and 14 conjunctival melanoma. Integrity of miRNA in tissues was evaluated in each sample with the preservation of miR126 expression in endothelial cells. Protein expression of MITF, IGF2R and KCNMA1 was assessed by immunohistochemistry. Statistical analysis was performed with JUMP 8,0 software. In situ hybridization and immunohistochemistry were assessed independently by two observers. Results There were 7 subepithelial nevi and 7 compound nevi. There were 5 female and 9 male. The population mean age was 48.7 ± 6.4 years (SEM). miR211 was found in 11 nevi (79%). MITF was expressed in all the nevi. IGF2R was found in 13 nevi. KCNMA1 was found in 57% of the nevi.The melanoma group was composed of 9 females and 5 males with a mean age of 67 ± 4.8 years (SEM). Using the recent TNM classification, 5 tumors were belonging to the T1, 3 to theT2 and 6 to the T3 categories. miR211 was found in 5 melanoma (36%). There was a significant downregulation of miR211 in the melanoma compared to the nevi (p=0,0219). MITF was found in 13 melanoma (93%). IGF2R and KCNMA1 were respectively found in 71% and 77% of the melanoma. There was no significant differential expression of MITF, KCNMA1 and IGF2R between the nevi and the melanoma as well as no association between miR211 expression and protein expression of two potential target genes Conclusions In vivo miR211 is significantly reduced in conjunctival melanoma compared to conjunctival nevi. No correlation between mir211 expression and two potential target genes KCNMA1 and IGF2R was observed.
