Interestingly, evaluation of her primary presentation, first recurrence and second recurrence showed an apparent change in HER2 amplification status.
Of the seven patients who progressed from grade 2 to grade 3, five were hTERT both at initial presentation and recurrence and 2 were hTERT at initial presentation and hTERT at recurrence.
The International Headache Society, in 2004, provided a thorough revision of guidelines for proper diagnosis of any head pain by defining, particularly for PHs, clinical characteristics, presentation and recurrence over time (ICHD-II, 2004) [3].
The prognosis of patients diagnosed with hepatocellular carcinoma (HCC) is often dismal, mainly due to late presentation, high recurrence rate, and frequent resistance to chemotherapy and radiotherapy.
The prognosis of patients diagnosed with HCC is often dismal, mainly due to the late presentation, high recurrence rate, and frequent resistance to chemotherapy and radiotherapy [3].
Previous analyses of paired isolates from index presentation and recurrence events using serology, antibiotic-resistance profiling, pulsed-field gel electrophoresis, and plasmid profiling identified recrudescence as the most likely driver of recurrent disease in Malawian HIV-infected patients [ 3].
Reflecting both this much reduced rate of relapse and the conserved tendency to early presentation of recurrence, our protocol reduces the frequency of investigation and follow-up visit at an earlier stage than the previously described for surveillance [III, B].
High prevalence rates of contralateral upper tract and urinary bladder involvements of UC in CKD, either at presentation or recurrence, raise concerns of the necessity and techniques as well as perioperative risk of complete urinary tract exenteration.
However, resistance to chemotherapy is a substantial problem, reflected in subsequent presentations with recurrences.
To shed light on the discrepancy between the advanced stage at presentation and high recurrence rate of well-differentiated thyroid cancer in children and the overall good survival.
Male sex and nonconventional subtype of tumor were related to a higher likelihood of poor chemotherapy response.The absence of metastases at initial presentation, negative local recurrence or metastases after treatment, and tumor response to chemotherapy are of independent prognostic value in osteosarcoma.
