Following this puts new work involving it at the top of your briefing, with a note saying why it is there. Links are taken from the source record, never inferred.
A single case report of an uncommon clinical scenario with no control group, comparative data, or systematic evidence; describes feasibility and tolerability in one patient but cannot establish efficacy or guide clinical practice.
A single case report documenting an unusual clinical phenomenon (phenotypic conversion in breast cancer metastasis) with descriptive pathology and treatment response, insufficient to establish efficacy or guide practice.
A single case report describing an extraordinarily rare metastatic pattern with anecdotal treatment response; raises questions about multi-site biomarker heterogeneity and sequential targeted therapy but provides no controlled evidence or generalizable outcomes.
A patient-reported survey study using descriptive statistics without a control group or comparator; establishes prevalence of reported misdiagnosis in metastatic invasive lobular cancer but lacks analytical rigor and hard clinical outcomes.
A single clinical case report without control group, quantified outcomes, or generalizable evidence on the effectiveness of combined treatment for adrenal metastases from colorectal cancer.
A single case report of an exceptionally rare presentation (urethral metastasis of therapy-induced neuroendocrine prostate cancer) treated with chemoradiotherapy, describing outcome in one patient without comparator or control group.
