[A Case of Triple Negative Breast Cancer with Successful Control of Recurrent Disease Activity for More than Ten Years].

A woman in her 70s underwent mastectomy plus axillary lymph node excision(Bt plus Ax)in December 2011 for left breast cancer classified as pT2N1M0, pStage ⅡB. The tumor was identified as an invasive ductal carcinoma(IDC), neural/ glial antigen 2(NG2), pT2(35 mm), INF γ, ly2, v0, g+, f+, s+, extensive intraductal component(EIC)-negative, ICT- positive, NCAT-positive, n(4/18), estrogen receptor(ER)-negative, progesterone receptor(PgR)-negative, human epidermal growth factor receptor 2(HER2)-negative, Ki-67 30-40%. Postoperative adjuvant fluorouracil plus epirubicin HCl plus cyclophosphamide(FEC)plus paclitaxel(PTX)therapy was administered.

Clinicopathological features of breast cancer patients with internal mammary and/or supraclavicular lymph node recurrence without distant metastasis.

Background: Internal mammary and/or supraclavicular (IM-SC) lymph node (LN) recurrence without distant metastasis (DM) in patients with breast cancer is rare, and there have been few reports on its clinical outcomes.

Methods: We enrolled 4237 patients with clinical stage I-IIIC breast cancer treated between January 2007 and December 2012. Clinicopathological features of patients with IM-SC LN recurrence and patients with DM were retrospectively reviewed.

Survival in Cytologically Proven Node-Positive Breast Cancer Patients with Nodal Pathological Complete Response after Neoadjuvant Chemotherapy.

Background: It is unknown whether patients with cytologically proven axillary node-positive breast cancer who achieve axillary pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) have comparable prognosis to patients with axillary pathological node-negative disease (pN-) without NAC.

Methods: We retrospectively reviewed the data of patients with cytologically proven axillary node-positive disease who received NAC and those with axillary pN- without NAC for control between January 2007 and December 2012. We compared outcomes according to response in the axilla to NAC and between patients with axillary pCR and matched pairs with axillary pN- without NAC using propensity scores.

[A case of pathologically complete response of esophageal carcinoma treated with low-dose 5-FU/CDDP as neoadjuvant chemotherapy].

The patient was a 75-year-old woman with advanced esophageal cancer and lymph-node swelling in the mediastinum(cStage RR). We administered preoperative chemotherapy(5-FU 500mg/body×10, CDDP 10mg/body×10). She received the two courses without showing any serious side effects.

[A case of gastric cancer with rhabdoid features showing better prognosis through S-1/CDDP chemotherapy].

Although gastric cancers(GCs)with rhabdoid features are rare, they are known to show a poorer prognosis compared with conventional GCs. Indeed, more than half of reported GCs with rhabdoid features died within 6 months after receiving any kind of initial treatment. Obviously, no effective chemotherapy has been reported.
