The variability of aggressiveness of grade 1 breast cancer

BACKGROUND

Grade 1 breast cancer represents the lowest grade of invasive breast cancer and is associated with a low risk of recurrence and distant metastasis. However, when grade 1 breast cancer is associated with lymph node involvement, the prognosis may be worse than that of grade 1 breast cancer without lymph node involvement.

METHOD

The study population included all patients who were managed in our institution between January 1, 2007 and December 31, 2013 for grade 1 breast cancer . We compared patients who had lymph node involvement to those who had no lymph node involvement.

RESULTS

During the study period 291 grade 1 carcinomas were included of which 23% had associated positive lymph node involvement. Overall survival did not differ significantly between patients without lymph node involvement and those with lymph node involvement, nor was there a significant difference in the risk of local recurrence free survival. However, a significant difference was found in survival without distant metastasis with a significant level of a p at 0.029.

CONCLUSION

Our findings confirm that tumor size and LVSI are strong predictors of axillary lymph node involvement, which is a key determinant of distant metastasis-free survival.

Patterns of Children's Relationships With Parents and Teachers in Grade 1: Links to Task Persistence and Performance

Our study aimed to investigate the patterns of children's relationships with their parents and teachers, the development of these relationships during Grade 1, and respective links to children's learning (in task persistence and performance). Parents of 350 children answered questionnaires about the quality of their relationships with their children; 25 teachers answered questions about children's task persistence at school and the quality of their relationships with their students; 350 children completed literacy and math performance tests; and six testers evaluated children's task persistence when completing those tests. All measures were administered twice: at the start and end of Grade 1. Latent profile analyses found two meaningful child profiles that were similar at the beginning and end of Grade 1: average relationship (89% at T1, 85% at T2) and conflictual relationship (11% at T1, 15% at T2) with parents and teachers. These profiles were highly stable throughout Grade 1, except for 15 children who moved from an average relationship to a conflictual relationship profile. This declining trajectory can be characterized by poor relationships with teachers and low task persistence at the end of Grade 1, although they did not perform any worse than other children. Finally, children exhibiting conflictual relationships with their parents and teachers at the beginning of Grade 1 performed worse on spelling and subtraction tasks and demonstrated lower task-persistent behavior at the end of Grade 1 than those with average (good) relationships with parents and teachers.

Grade 1 Spetzler and Martin cerebral ruptured arteriovenous malformations treated by microsurgery: Poor functional outcome is related to injury from haemorrhage

INTRODUCTION

Ruptured arteriovenous malformations (rAVM) are life-threatening diseases.

OBJECTIVE

To evaluate the outcome of patients with grade 1 SPM rAVM after microsurgical treatment.

MATERIALS AND METHOD

We retrospectively included 64 consecutive operated patients with a grade 1 SPM rAVM in our institution between 2002 and 2012. Complications related to the surgical procedure were recorded. All patients were re-evaluated 3months after treatment using the modified Rankin Scale score (mRS). Persistent neurological disorders were evaluated 1year after bleeding. Conventional cerebral angiography was performed for each patient immediately after surgical treatment and 1year later.

RESULTS

The mean age at diagnosis was 30.8 years. Initial WFNS score was grade 1 in 25 patients, grade 2 in 11 patients, grade 3 in 10 patients, grade 4 in 9 patients and grade 5 in 9 patients. No remnant was left and a new surgery was performed only in a single patient who was initially operated-on under emergency conditions with limited preoperative investigations due to a poor clinical grade. Early postoperative complications related to the surgical procedure were recorded in 7 patients. The mRS score 3months after treatment was ≤2 in 53 patients (83%). Persistent neurological disorders were recorded in 40 patients (62.5%). High initial WFNS score (>2) and the hydrocephalus were significantly associated (P<0.05) to a bad functional outcome (mRS>2).

CONCLUSION

Grade 1 rAVM is a life-threatening disease concerning in most cases young patients. Long-term morbidity is often related to the hemorrhagic brain damage and rarely to the AVM resection.

Appropriateness of systemic treatments in unresectable metastatic well-differentiated pancreatic neuroendocrine tumors

AIM: To evaluate systemic treatment choices in unresectable metastatic well-differentiated pancreatic neuroendocrine tumors (PNETs) and provide consensus treatment recommendations.

METHODS: Systemic treatment options for pancreatic neuroendocrine tumors have expanded in recent years to include somatostatin analogs, angiogenesis inhibitors, inhibitors of mammalian target of rapamycin and cytotoxic agents. At this time, there is little data to guide treatment selection and sequence. We therefore assembled a panel of expert physicians to evaluate systemic treatment choices and provide consensus treatment recommendations. Treatment appropriateness ratings were collected using the RAND/UCLA modified Delphi process. After studying the literature, a multidisciplinary panel of 10 physicians assessed the appropriateness of various medical treatment scenarios on a 1-9 scale. Ratings were done both before and after an extended discussion of the evidence. Quantitative measurements of agreement were made and consensus statements developed from the second round ratings.

RESULTS: Specialties represented were medical and surgical oncology, interventional radiology, and gastroenterology. Panelists had practiced for a mean of 15.5 years (range: 6-33). Among 202 rated scenarios, disagreement decreased from 13.2% (26 scenarios) before the face-to-face discussion of evidence to 1% (2) after. In the final ratings, 46.5% (94 scenarios) were rated inappropriate, 21.8% (44) were uncertain, and 30.7% (62) were appropriate. Consensus statements from the scenarios included: (1) it is appropriate to use somatostatin analogs as first line therapy in patients with hormonally functional tumors and may be appropriate in patients who are asymptomatic; (2) it is appropriate to use everolimus, sunitinib, or cytotoxic chemotherapy therapy as first line therapy in patients with symptomatic or progressive tumors; and (3) beyond first line, these same agents can be used. In patients with uncontrolled secretory symptoms, octreotide LAR doses can be titrated up to 60 mg every 4 wk or up to 40 mg every 3 or 4 wk.

CONCLUSION: Using the Delphi process allowed physician experts to systematically obtain a consensus on the appropriateness of a variety of medical therapies in patients with PNETs.
