Gallbladder cancer: Progress in the Indian subcontinent

Table 4 Studies on diagnostic methods and imaging

Serial No.	Sample size	Findings	Ref.
1	-	PET-CT can be used to rule out metastatic disease and for post-therapy surveillance for recurrence in patients of GBC	Bisht et al[147]
2	GBC (38)	Potential utility of CT texture-based radiomics analysis in patients with GBC.	Gupta et al[148]
3	GBC (141)	Raised levels of serum CA19-9 beyond 20 units/mL should be used for prognostication purposes after EC	Agrawal et al[149]
4	GBC (141)	NMR-based methods can be used as a diagnostic modality for GBC	Sharma et al[150]
5	GBC (41)	CEA expression may help in diagnosis of GBC	Mondal et al[151]
6	GBC (203)	Discontinuous mucosal lining, diffuse wall thickening, intramural nodules, and cholelithiasis may indicate XGC rather than gallbladder carcinoma	Sureka et al[152]
7	GBC (74)	Duodenal involvement significantly decreases resectability but does not preclude resection	Kalayarasan et al[153]
8	XGC (31)	Mass-forming XGC mimics GBC	Agarwal et al[154]
9	GBC (117)	CA 242 is a promising tumor marker for GBC and performs better than CEA and CA19-9.	Rana et al[155]
10	GBC (15)	Dynamic MRI with MRCP is a reliable method of showing gall bladder carcinoma.	Kaza et al[156]
11	GBC (60)	Color Doppler USG together can improve pickup rate of GBC	Pradhan et al[157]

PET: Positron emission tomography; CT: Computed tomography; GBC: Gallbladder cancer; MRI: Magnetic resonance imaging; MRCP: Magnetic resonance cholangiopancreatography.
