some good news is that (1) your viral load (VL) fluctuations are almost certainly insignificant and in no way indicative of deterioration (+ - 0.5 log units is generally considered noise, and in any case increased VL does not imply increased damage)(2) there is no particular difficulty to treating 1b over other geno 1 subtypes (3) the prospects for treating are improving rapidly (4) there are many here with stage 4 who have successfully gone to SVR.
The not so good news is that stage 1-2 to stage 4 progression in 4 years. Before committing to starting tx now, rather than waiting for the 1st gen PIS (about a year) it's worth confirming that diagnosis. Rapid progression happens but is rare, more common in a setting of hiv/hcv co-infection. Stage 4 is the beginning of cirrhosis, and cirrhosis is almost invariably marked by additional indicators. Here's a list of things to pursue:
- if you can obtain slides from the previous bx take those and your current ones to another pathologist for a 2nd opinion, tracking progression (if possible, handle delivery of the slides yourself so the previous reports are not included to avoid bias)
- ask for an ultrasound measuring spleen and portal vein diameter; advanced fibrosis is often accompanied by an enlarged spleen, or the US may detect nodules indicative or cirrhosis
- check your APRI score (AST/platelet) ratio. Low platelets or an APRI > 1.5 are indicators of fibrosis
- check your bilirubin, albumin and INR scores. Elevated bilirubin, or INR or low albumin are other common indicators
- since you are in FL, you may be able to have a Fibroscan, a device which measures stiffness of the liver and samples a much larger area than a bx (not yet FDA aproved in the US). See thread

- a simple, composite, serum based test such as Fibrosure can also be used to confirm advanced fibrosis.
Sorry if the list is long, but before jumping into tx it's worth investigating that diagnosis. Either way, it's time to treat, but the results of the above will help you decide if the time is soon, or *now*.
